HARDOX SAVES ENERGY AND RESOURCES EVERY TRIP, EVERY LOAD, EVERY TIME Steel is heavy and requires a lot of energy to produce. That’s why it’s important to use as little as possible without sacrificing strength and performance.

The strength-to-weight advantages of using Hardox come into play in many other areas such as road construction, recycling and mining.

One example: The truck container. Reduced weight from using Hardox® wear plate instead of regular steel can be translated into an increased load capacity by 10% or more.

Making Hardox is our contribution to a stronger, lighter and more sustainable world – whatever the application.

That’s equivalent to removing one out of ten trucks from our roads, saving fuel and reducing emissions to the same degree.

editor’s letter

PDAC diary n my way into Toronto for the latest PDAC, I reached out to a geologist friend of mine to be sure we could meet up if even for a few minutes. He has experience working on projects in Canada, Latin America, and North Africa, and has been my barometer for exploration activity. Both of us fathers of young children, I have been anxious on his behalf as the work has dried up and he would respond to my questions with a shake of his head and change the subject. I thought by reaching out early I would have the chance to get a few more details on the work he is doing in Northern Quebec with his newly formed company. It became clear on day three of the event, after many failed attempts to connect, that his time was at a premium. This year, he confirmed by text, there is plenty of money out there. Some drillers I spoke to said business inquiries had begun coming in, but were still not prepared to say they were now in that long-promised light at the end of the tunnel. One contact from an equipment manufacturer focused on mine production, however, confided that they are now working at full capacity after orders began picking up in the fall.

Finalist

After a few years of industry spokespeople urging a cautious optimism, the times have caught up with that sentiment. As for the caution, there are certainly things to be wary of. Slow economic growth globally, relatively fewer people of working age around the world and an enormous amount of household debt in China were three such trends that Wood Mackenzie economist Jon Butcher highlighted in his review of macroeconomics at the conference. That said, while measured growth may not yield as many of those enormously profitable “ten bagger” mining stocks that become the stuff of legend, it is likely a better environment to get projects underway. Finally, congratulations are due to Roy Slack and Cementation Canada for capturing the imagination of the judges and attendees of the Disrupt Mining challenge with his presentation of the company’s idea for a pump-driven injection hoisting system, the details of which you can find on our YouTube channel. It is definitely worth a watch.

president’s notes

Bring back the miners

“I feel passionately about the benefits of being a CIM member and want to encourage as many people to join as possible.”

Near the start of my tenure as CIM President, I met Dick McIvor at a Sudbury Branch meeting. Dick is a CIM Life Member and hoisting specialist. He charged me with the task to “bring back the miners”. By this, he meant CIM needed to get more people from the operations to come out to the branch meetings: geologists, mining engineers, processors, managers and other mining personnel. In turn, this would stimulate growth in participation from our industry consultants, contractors and suppliers. Also Dick wanted to see more senior mining leaders participating locally with CIM, to encourage the new generation of young professionals to participate. Many times over my career, I have been rewarded by being part of our association, from networking to learning technical knowledge, leadership and organizational skills. I feel passionately about the benefits of being a CIM member and want to encourage as many people to join as possible. Like the mining industry as a whole, CIM has faced many challenges in the downturn over the last six years. Our membership numbers are down and in turn our finances are down. We need to restore a critical mass of members in order to continue to provide the high-quality services CIM offers. To that end we have an action plan for membership and our council and national office are concentrating on this as our top priority. Mindful of my assignment, I have traveled to CIM events throughout the country and have worked hard to encourage everyone from former colleagues of my generation through to students to participate in CIM. I have encouraged diversity to have a better balance of women, First Nations, visible minorities and others involved in CIM and our industry. If you are reading this note, you are likely already a CIM National member and I am preaching to the converted. However, my request to you is to engage your fellow colleagues who are not members. Invite them to branch meetings and social events. Share with them the benefits of being a National member: the networking opportunities, conventions, technical and professional development through OneMine and EduMine, the digital and print communications, the list goes on. Please join me in the quest to “bring back the miners” to CIM!

Process monitoring technology is the eyes and ears of any industrial process, with accurate instrumentation the key to reliability, safety and quick diagnostics. Endress+Hauser’s Proline 300/500 flow measuring technology offers continuous sensorassisted Heartbeat monitoring of pipe flow, and data that can be retrieved from the control room or a laptop without the need for additional hardware or software. This ensures that reliable data is readily available at all times. “If for some reason a test parameter falls out of specification an alarm will appear, indicating in clear text what the issue is and what corrective action needs to be taken,” said John Yates, marketing manager with Endress+Hauser Canada. Proline 300/500 not only measures flow, it ensures plant operators get a wealth of process data for monitoring, which leads to fewer unexpected periods of downtime and more efficient process control. Eliminating the need for maintenance technicians to verify performance in the field keeps them out of potentially unsafe environments and can reduce verification time by up to 90 per cent.

It is well known that uncoated equipment will corrode in the harsh environments in which miners operate. But the battle against the elements may have a fancy new coat of arms. Sherwin-Williams’ Dura-Plate 301 Series epoxy systems can be applied over damp and rusted substrates at just a few degrees above freezing. These innovations can prevent rust and extend the life of assets by broadening feasible coating schedules, allowing for more cost-effective maintenance and less overall downtime. “Especially in the mining industry, you can have some very aggressive environments that will eat your steel and cause it to corrode at a much faster rate than normal,” said Bruce Toews, global market director for process industries with SherwinWilliams. “Traditional epoxies cannot be applied below 50 F [10 C], but with this product you can work substantially below that, even over damp steel.” These coatings can be applied over a wide range of surface preparation techniques, including water jetting, abrasive blasting and power tool cleaning, allowing for quicker in-field maintenance and lower labour costs.

Brand new coat

From data to information Logging and storing drilling and sample data in simple programs like Excel or Access can be messy and inefficient for geologists and executives alike. Micromine’s Geobank 2017 data solution software offers geologists a secure and flexible platform for capturing information in the field, managing said information, and modeling solutions for generating value from the extracted data. “Geobank Mobile in the field standardizes the data collection process, and having automated synchronization to the master Geobank database ensures that the resource geologists are seeing data as soon as it is logged,” said product strategy manager Mark Gabbitus. “It manages the input of data not just from the field but also from external data sources such as laboratories, and allows the client to write their own rules to control what data can go into the database and what needs further verification.” Managing data in a secure database via a server, rather than a single file or laptop, also allows for easy recovery in case of hardware crash or malfunction.

Developments A fair shake at justice B.C. court sides with Guatemalan protesters in jurisdiction dispute with Tahoe Resources A British Columbia appeals court ruled Guatemalan protesters who say they were shot at by Tahoe Resources’ private security guards can proceed with their lawsuit against the miner in Canadian court. The ruling, which reverses a B.C. Supreme Court decision that sided with Tahoe, is significant because it shows the Canadian courts’ willingness to consider the risk of an unfair trial before passing off a case to a foreign jurisdiction. “It’s a really strong endorsement that access to justice matters,” said lawyer Joe Fiorante, who is representing the seven Guatemalan men. “That had not been expressly considered as a factor by any appellate court before this.” The ruling is one of three recent cases in which Canadian courts have elected to keep jurisdiction over allegations involving Canadian mining companies’ actions abroad. The decisions have caught the attention of human rights activists in developing countries looking for the best avenues to get justice, as well as signalled to companies that if they fall short on corporate social responsibility overseas, they could still be held accountable at home. Tahoe plans to defend itself regardless of where the case is heard. But spokesperson Mark Utting said the company still believes the case is better suited to a Guatemalan court, and is considering whether to appeal the decision. “It’s where the mine is, it’s where

In 2013 seven local men joined a protest outside of Tahoe’s Escobal mine in Guatemala (pictured), where they say they were shot at close range by security guards.

the events were and the people are from Guatemala,” Utting said. The case revolves around an April 27, 2013 incident in which seven local men, mostly farmers, concerned about water consumption and possible contamination, joined a “peaceful protest” outside the Escobal silver mine, which is operated by Minera San Rafael, a wholly owned subsidiary of Tahoe. A statement of claim filed in 2014 alleges the men were shot at close range by security guards and suffered “serious injuries, including wounds to their backs, faces, feet and legs.” The protesters allege the shooting was planned, ordered and directed by Tahoe’s Guatemala security manager Alberto Rotondo Dall’orso, who faces criminal charges in Guatemala but fled to his native Peru. He was caught by police and now faces extradition to Guatemala.

The B.C. Court of Appeal agreed with the protesters’ lawyers that Guatemala was not the best place for the civil case to proceed because of three reasons: the statute of limitations had expired in Guatemala; under the Guatemalan system, the plaintiffs would not have access to Tahoe’s internal documents that could show decisions and policies surrounding private security at Escobal; and Guatemala does not have structures in place to ensure judges are truly independent, and so there is a risk of an unfair trial in a case of farmers going up against a large corporation whose mine is backed by the government. “In characterizing the appellants’ claim as a personal injury case, the (B.C. Supreme Court) judge was insufficiently attentive to the context in which the conflict arose,” Justice Nicole J. Garson wrote in her decision. March/April 2017 • Mars/Avril 2017 | 15

“This claim is not akin to a traffic accident. Rather, it arose in a highly politicized environment surrounding the government’s permitting of a large foreign-owned mining operation in rural Guatemala.” By default, Canadian courts have jurisdiction over Canadian companies no matter where they operate. The onus is on the companies to show why a foreign court is better placed to hear a case against them, and Canadian courts have mostly agreed with them in the past. But now multiple cases are signalling a shift. Last year, a B.C. court ruled Eritrean workers who claimed Vancouver-based Nevsun Resources was complicit in the government’s use of slave labour could proceed with their lawsuit in Canada. Nevsun appealed that decision and the B.C. Court of Appeal will hear the case in September. In Ontario, three lawsuits blaming HudBay Minerals for a killing, a shooting injury and gang rapes in Guatemala are moving to trial. “This issue comes up more and more often,” said Justin Connidis, who teaches mining law and policy at Queen’s University. “Aggrieved parties (such as NGOs) are becoming more aware of their rights and the best ways to proceed.” Workers or activists taking up claims against companies can be assured they will get a fair trial in Canada’s “independent, knowledgeable and skilled tribunal,” Connidis said. “Canadian courts have this reputation, possibly more so than U.S. courts, which have elected judges and certainly more so than many countries with evolving legal and political systems.” What Canadian companies should take away from this, Connidis said, is to make sure their operations fall in line with the United Nations Declaration on the Rights of Indigenous Peoples, which prohibits forcibly removing indigenous people from their land, among other provisions. “In (developing) countries with governments of questionable integrity, it is not enough to rely on permissions granted by those governments if they are not in compliance with the UN Declaration,” he said. CIM

Taseko contends that Natural Resources Canada modeled the wrong tailings storage facility design in its submission to the CEAA panel on New Prosperity (site pictured above).

Taseko questions constitutionality of environmental assessment act In an effort to revive its New Prosperity project, Taseko Mines brought a constitutional challenge against the Canadian Environmental Assessment Act (CEAA) under which the project was evaluated. In its applications for back-to-back judicial reviews of the decision to reject New Prosperity, which were heard in federal court in November and concluded in early February, Taseko argued that two sections of the Act fall outside of the powers of Parliament and should therefore have no effect. What is at issue in the judicial reviews is “the principles of natural justice and administrative fairness, the duty to act in a procedurally fair manner,” said Brian Battison, Taseko’s vicepresident of corporate affairs. “That was the duty that the federal government had, and that they failed to live up to.” Within Section 5 of the Act, it says that environmental effects on Indigenous Peoples’ health and socio-economic conditions; physical and cultural heritage; use of land and resources for traditional purposes; and structures or sites with historical, archaeological, paleontological or architectural significance should be taken into account when evaluating a project.

The next section says that a project proponent may not carry out any part of their project “if that act or thing may cause an environmental effect” to any of the places, people and habitats listed in Section 5 (which also covers federal lands, and fish, aquatic species and bird habitats). Taseko argued that the sections trample over the authority and discretion of the provincial government “even where the provincial Crown met its duty to consult with aboriginal peoples before approval was granted,” the company stated in court filings viewed by CIM Magazine. The company argued that striking the sections would not infringe on the rights of indigenous groups, as consultation is a duty of both provincial and federal governments. However the Tsilhqot’in Nation, whose declared title land is close to the project, said in a press release that the constitutional challenge amounts to an argument that the Act “goes too far in protecting the interests of aboriginal peoples.” Battison rejected that argument. “That’s not true at all,” he said. “We have never made that claim.” The Tsilhqot’in went to court in late January to oppose the company’s attempt to save New Prosperity. In a press release they stated that the company “is attempting to further reduce the protection of our already gutted federal environmental laws, particularly as they apply to Aboriginal people.”

materials to the EU. But for the thousands of companies in Canada’s mining supply and services (MSS) sector, the benefits are not as clear.

The federal government has already blocked the copper-gold project twice due to environmental concerns. The first time, in 2010, the CEAA panel rejected what was then the Prosperity project based on the use of Fish Lake for tailings storage. The second review considered a revised project, called New Prosperity, which planned to avoid the use of Fish Lake. The company contends that, in its submission to the review panel for New Prosperity, Natural Resources Canada modeled the wrong tailings storage facility design, which did not take into account mitigation measures Taseko had included, leading to the minister’s decision that the project was not justifiable. Taseko asked to have the minister’s decision quashed, and the panel’s findings invalidated. Taseko also took issue with a closeddoor meeting held between the Tsilhqot’in National Government and the minister after the panel’s review had concluded, as well as the inclusion of a 59page submission opposing the project included in the minister’s briefing notes on New Prosperity, which the company did not have the opportunity to review, nor to include its own follow up brief. Taseko also filed a lawsuit against the federal government in B.C. Supreme Court last February, arguing the government and environment minister “failed to meet the legal duties that were owed to Taseko” in blocking New Prosperity. Battison said the civil claim, which is seeking unspecified damages, – Kelsey Rolfe is still ongoing.

FROM THE WIRE Trevali Mining Corporation announced on Feb. 1 a $20 million investment in the mining fleet at its Caribou zinc mine in New Brunswick. The partnership with Sandvik Mining will include procurement of new underground mining equipment. Trevali will operate and manage mining operations, while Sandvik will be responsible for maintenance of the fleet. Brendan Bell will step down as CEO and member of the board of directors at Dominion Diamond on June 30, 2017, allowing time for a successor to be identified. Bell cited personal and family reasons for his departure, due to the from move office’s corporate Yellowknife to Calgary. Due to difficulties with pending permits, Detour Gold announced that mining would not begin at the West Detour project in January 2018, as per current mine plans. The company will instead file a new life of mine plan, as well as push to have its provincial environmental study report upheld, despite requests from indigenous partners for a federal environmental assessment process. ExxonMobil reported on Feb. 22 that its oil and gas reserves dropped 19 per cent last year to 20 billion oil-equivalent barrels due to low oil prices, forcing the company to write down 3.5 billion barrels of heavy bitumen oilsands reserves at the Kearl field in Alberta. This is the largest drop reported by a major international oil company for at least a decade. B.C.-based MineSense Technologies closed a $19 million financing deal on Feb. 15, led by Aurus Ventures and Caterpillar Venture Capital, the equipment giant’s venture capital arm. Chrysalix Venture Capital, Cycle Capital Management, Prelude Ventures and Export Development Canada also participated in the financing. The company’s new developments promise innovative real-time sensor technology and data analytics software which improves ore-waste classification and productivity while decreasing overall environmental footprint. 18 | CIM Magazine | Vol. 12, No. 2

just another trade agreement and a step in the right direction. We’ll wait and see once it passes the Senate and becomes real.” CAMESE is considering how CETA will impact the Canadian MSS sector on behalf of its 300 member companies. About 70 per cent of these companies are currently involved in exporting goods, mainly to the United States and Mexico, and South American markets. “With just half a per cent of the world’s population and 2.5 per cent of the global GDP, Canada’s a small part of the big picture,” said McEachern. Canada relies heavily on trade, he said, but is recognized as a resource sector leader, particularly when it comes to quality and adherence to social and environmental regulations. “Reducing the complexity of moving products across borders and reducing duties and costs will be a benefit,” said McEachern. “Improved labour mobility will benefit companies offering engineering services, for example, and the simplification of entering markets to identify and negotiate deals will benefit companies looking at the European market for growth.” The EU Parliament voted 408 to 254 in favour of CETA in Strasbourg, France. Both Canada and the EU will now complete their respective legislative and regulatory processes to bring the agreement into force by spring – Kylie Williams 2017.

BHP Billiton and Vale reach agreement on Samarco tailings failure Samarco and its parent companies, BHP Billiton and Vale, have entered into a preliminary agreement with Brazilian federal prosecutors to settle the civil claim over the 2015 Fundão tailings dam failure for roughly US$47.5 billion. The amount will cover social, environmental and economic remediation and compensation. “The preliminary agreement we signed [in January] agrees on a process for the negotiations to settle this,” said

Ruban Yogarajah, a spokesperson for BHP Billiton. It succeeds a previous attempt last March by the three companies, Brazil’s federal government and two state governments to settle terms for the implementation of environmental and socioeconomic programs to assist and rebuild communities in the states of Minas Gerais and Espírito Santo, which were impacted by the dam collapse. The initial 2016 agreement created the Renova Foundation to manage the work and settled a US$6-billion civil claim. But despite being agreed upon by federal and state governments, federal prosecutors never signed on to this deal, demanding a significantly higher settlement in a separate suit, reportedly based on the clean-up costs of BP following the Deepwater Horizon oil spill in 2010. This new preliminary agreement requires Samarco, Vale and BHP to advance US$60 million of the funding obligations within 90 days to the affected municipalities of Barra Longa, Rio Doce, Santa Cruz do Escalvado, and Ponte Nova. “It includes the appointment of experts to advise the prosecutors, and any revisions to the Renova Foundation’s programs and monitoring,” said Yogarajah. Under the timeframe established in the preliminary agreement, a final settlement arrangement with federal prosecutors is expected to occur by the end of June. If not, the courts could reinstate a US$370-million injunction clause. Last August BHP announced a record loss of US$6.4 billion due to the dam collapse as well as a slump in overall commodity prices. A month later, Samarco announced plans to restructure debts after failing to make a US$13.4-million payment to international creditors. Yogarajah said it was possible that operations at Samarco could restart within the year – the company employs some 5,000 people in the region. However, he said that any future “negotiations would depend on several […] licensing and commercial processes yet to be fully determined.” He declined to comment further. – David Meffe

First weeks of Trump administration include drastic changes for mining, oil and gas sectors

De Beers Canada halted plans for the proposed Tango Extension at the Victor mine in northern Ontario after failing to get support from the nearby Attawapiskat First Nation. According to company spokesperson Tom Ormsby, the company is looking at processing low-grade stockpiles on site to stay active until 2018, or innovating technology to take 40 metres of high grade ore at the very bottom of the pit, which is currently too narrow for traditional mining methods.

Surrounded by members of his new administration, President Donald Trump reversed Barack Obama’s halt on the Keystone XL pipeline on Jan. 24. The pipeline will send more than 800,000 barrels a day from Alberta to refineries in Texas and the Gulf Coast.

If the first weeks are any indication of what is to follow, the policies of United States President Donald Trump’s administration could have lasting impacts on the Canadian petroleum industry, global transparency regulations, and North American trade overall. Within days of assuming the presidency on Jan. 20, Trump signed a swift streak of executive orders, including one immediately reversing his predecessor’s veto on the controversial Keystone XL pipeline. The pipeline will extend from Alberta to refineries in Texas and the Gulf Coast, passing through six states along the way. By 2014, the pipeline had become symbolic of the ongoing battles between President Barack Obama’s administration and a newly Republican-controlled Senate, in addition to the clash between environmentalists and the fossil fuel industry. Both the federal Liberal and Conservative parties, in addition to Natural

Resources Canada and the National Energy Board, have been supportive of the pipeline and its promise to create some 2,200 Canadian jobs in the construction phase alone. In part due to falling oil prices, Alberta’s unemployment rate rose to 7.4 per cent in 2016 – the highest since 1996. The pipeline also puts Canada’s oil sands industry on more stable footing in the international market and signals the potential for future pipelines with farther reach. “In the past, Canada has been seen as a country that’s almost landlocked, since we export almost no oil or gas outside of North America. So these pipelines should help attract some foreign investment since Canada can now have greater access to the U.S. Gulf Coast, and potentially greater access to the west coast, which in turn gives us more access to Asia,” said Reynold Tetzlaff, national energy leader with PricewaterhouseCoopers. “Keystone shows the world that Canada actually has the

Iamgold announced positive results of a preliminary economic assessment for its Côté Gold Project in northern Ontario, which would have a 21-year mine life producing 302,000 ounces of gold a year on average, at an average all-in sustaining cost of $686/oz. The company outlined an estimated 12.9 per cent after-tax internal rate of return assuming a $1,200-per-ounce gold price. Additional positive environmental assessments from federal and provincial governments have cleared the way for the company to apply for development permits following a pre-feasibility study. New Gold reported on Jan. 30 that its Rainy River gold project in Ontario will cost at least $195 million more than expected, and production will begin in September, three months later than planned, leading the company to enter into bought deal financing that will raise $150 million for construction. The company also announced several management changes: Randall Oliphant will step down as executive chairman, Ian Pearce will become non-executive chair of the board, and Hannes Portmann will take on the mantle of both President and CEO, replacing Robert Gallagher. Agnico Eagle announced on Feb. 15 that the Amaruq satellite deposit at Meadowbank and the Meliadine project, both in Nunavut, were approved by the company’s board of directors. Both operations are expected to start production in the third quarter of 2019, with Meliadine scheduled to begin a year earlier than anticipated.

ties where those taxes and royalties are generated through mining, or oil and gas operations?” Jabara said. “So it provides those local communities that additional transparency and visibility into those payments so they’re then able to hold their elected representatives accountable for how that money is being spent, or not. “We’ll continue to do that regardless of whether there is legislation requiring it.” There are also fears Trump’s touted ‘America First’ policy could put Canadian exporters at a disadvantage. When it comes to global market access, any trade tariffs or abolition of regulations for U.S. companies puts Canadian retailers at a competitive disadvantage. Throughout the campaign and in his first few weeks in office, Trump criticized the North American Free Trade Agreement (NAFTA) as the “worst trade deal ever approved in this country,” vowing on Twitter to “tear it up” if he could not renegotiate and “make a great deal.” However Mining Association of Canada CEO Pierre Gratton doubts

whether miners should worry about a renegotiation affecting them. “NAFTA is about products flowing across borders. At the present time, we don’t see mineral products being a target for any kind of border tax. The United States imports a lot of iron ore,” Gratton said. “They’d be making their manufacturing sector less competitive if they imposed a border tax on our products.” Following a trade mission to Mexico in January (see story pg. 21), Canadian Minister of Natural Resources Jim Carr declined to comment on NAFTA renegotiations without a clear understanding of U.S. intentions. However, he acknowledged the possibility of energy taking on a unique role in future free trade talks. “We continue to make the case that the integration of the energy sector continentally is in the interest of all three governments, and that’s what we said when we responded to President Trump’s executive order on Keystone XL,” Carr said. “In this particular case, what’s good for one country is good for the other.” CIM Courtesy of Cameco Corporation

ability to get some of these infrastructure projects done, which we haven’t shown in the past five years, to our frustration.” Trump’s embattled order to ban citizens of several Muslim-majority nations could also alienate some of the U.S.’s traditional OPEC suppliers, making Canadian crude all the more appealing, according to Canadian Association of Petroleum Producers president Tim McMillan. “When given the option between granting access for Canadian oil to international markets and continuing to meet demand with Saudi Arabian, Venezuelan, Iraqi, and Nigerian oil, the choice is obvious,” he stated in a press release. Trump’s promise to eliminate regulations stymieing the extractive industry could have far-reaching consequences. On Feb. 14, the President used the Congressional Review Act to expunge elements of the Dodd-Frank Act, which required oil and gas and mining companies to report payments to foreign governments. For years extractive industry lobbyists argued that reporting requirements left American firms unable to compete with other international companies unfettered by such transparency measures. Yet the regulations were primarily aimed at curbing corruption in developing nations where government graft is commonplace and possible conflicts of interest are abundant. While the Extractive Industries Transparency Initiative (EITI) remains a global standard for transparency, membership in its ranks remains voluntary and ultimately unbinding. Omar Jabara, a spokesperson for Colorado-based Newmont Mining, a founding signatory of EITI with active gold mines in six countries, said repealing Dodd-Frank will have a noted impact on revenue transparency in the mining industry, but Newmont will continue to disclose payments. “[Dodd-Frank] helps keep governments accountable, in terms of the amount of money they receive and what they do with it. Are they reinvesting that money in the local communi-

Amidst a high-profile contract termination, Cameco will be cutting 120 employees at the McArthur River, Key Lake and Cigar Lake operations in Northern Saskatchewan.

Cameco vows to fight TEPCO contract termination Bear markets continue to plague Canada’s largest uranium miner as Cameco announced more layoffs at its

Canadian operations, net earnings lower than analyst expectations and a contract dispute with the Tokyo Electric Power Company (TEPCO) in early 2017. TEPCO issued a termination notice for a uranium supply contract in

January, which Cameco rejected. The Japanese energy giant stated that an event of “force majeure” has occurred, since it has been unable to operate its nuclear generating plants for 18 consecutive months due to government regulations arising from the Fukushima nuclear disaster in 2011. TEPCO already received and paid for 2.2 million pounds of uranium since deliveries began in 2014, and the termination would affect approximately 9.3 million pounds of stock through 2028, worth approximately $1.3 billion. If negotiations fail to resolve the dispute, the case could move on to binding arbitration. “We’ve been dealing with the general risk of contract non-performance due to Fukushima for nearly six years now,” Cameco senior vice-president and CFO Grant Isaac said in a conference call, noting that similar contract challenges had been successfully defended by the company in the past. “We also believe that the further we get away from the event, the lower the risk that that event can be legitimately used to justify contract non-performance.” This news came just days after Cameco announced plans to lay off 120 employees at the McArthur River, Key Lake and Cigar Lake operations – about 10 per cent of its total workforce. The company has also decreased pickup points for its commuter service in order to cut costs. These measures followed the shutdown of operations at Rabbit Lake and the cessation of most U.S. operations last April, which cut roughly 500 positions. In the same statement, Cameco also chided the discrepancy between analysts’ net earnings estimates for the company and its own significantly lower expectations for 2016. On Feb. 9, the company announced a net loss of $62 million largely due to impairment charges of $362 million caused by the Rabbit Lake and Kintyre projects. Uranium prices have fallen 50 per cent since 2011, along with the stock value and overall profitability of global producers. Public perceptions of the nuclear industry have also been

Major manufacturers hike prices for off-the-road tires Several major tire manufacturers announced significant price increases in February, which will affect consumer and commercial tires, as well as off-the-road (OTR) tires used by most heavy mining equipment. Yokohama Tire Corp. and Bridgestone announced a seven- and eightper-cent increase on all tires, respectively, citing rising raw material prices and other costs related to freighting and overall operations. Numerous other manufacturers, including Michelin, Goodyear, Alliance Tire Group, Toyo Tires and Kumho Tire, also announced around the same time that they would raise prices. “Yokohama hasn’t raised OTR tire prices in close to five years. In that timeframe, the cost of just about everything has gone up, including our base raw materials,” said Tim Easter, director of OTR sales for Yokohama. “We’ve reached a threshold where the effects

of the rising costs of raw materials, freight and operations left us with no other option but to adjust our pricing to the market.” Natural rubber prices reached a record low in January 2016, but began to spike in October, more than doubling in just a few months. The Association for Natural Rubber Producing Countries (ANRPC) attributed the spike, and its expectation that prices will continue to increase in 2017, to weather problems affecting supply, pointing to floods in 12 southern Thailand provinces. Rachel Withers, a spokesperson for Bridgestone, also noted a significant increase in the price of butadiene, an essential feedstock used in the production of synthetic rubber. – D. Meffe

in water management, energy efficiency, mine closure and community monitoring. Minister of Natural Resources Jim Carr said in a call with media that while there remained many challenges to bilateral mineral trade, including security, land access and taxation, both countries shared a desire to create middle class jobs. Last July, Primero Mining asked the government of Canada to intervene in a dispute with Mexico in which it claimed authorities were improperly collecting taxes on the sale of its silver. More than 36,000 Canadian companies currently operate in Mexico, and mining firms account for 70 per cent of foreign direct investment in the country, largely thanks to bilateral benefits guaranteed by the North American Free Trade Agreement (NAFTA). The trade mission came as United States President Donald Trump called for NAFTA renegotiations with Mexico, and for “tweaks” to Canada’s terms. “For Canada to have been there at this time, and looking to deepen its relationship with Mexico, was very welcomed by the Mexican government,” said Mining Association of Canada CEO Pierre Gratton, who was part of the delegation. “The timing couldn’t have been better, though it was coinci– D.

research groups – and a multidisciplinary approach. Fragomeni also pointed to the many different research initiatives in mining as a model for furthering R&D in the industry, in particular Canada’s Oil Sands Innovation Alliance. “They have a model where there is less of a focus on intellectual property and more of a focus on solving problems that are significant to the industry,” he said. Going forward, he said he sees three areas of opportunity for the mineral processing sector: the internet of things and big data; pre-concentration; and process mineralogy and geometallurgy. Throughout the conference, operators and vendors presented on some of the cutting-edge projects they are undertaking. Simon Hille, vicepresident of metallurgy and process at Goldcorp, gave a project update on the company’s pyrite leach project at its Peñasquito mine aimed to recover gold and silver from zinc tailings. “It’s a trend-setting project that’s actually being built,” CMP 2017 chair Scott Martin told CIM Magazine. The student program, which has always been strong at CMP, added a mentorship program this year. “We paired [students] with industry people who were like their guides throughout the conference,” explained Martin. The idea was to encourage more student networking and participation in the conference events.

CIM supports Fort McMurray community after wildfires The CIM national office and its affiliated societies and branches donated just over $110,000 to the relief effort in Fort McMurray following the wildfires that broke out in the Regional Municipality of Wood Buffalo, Alberta, last May.

The institute’s Fort McMurray Fire Relief Fund has been divided between five local charities: the Northern Lights Health Foundation, the Wood Buffalo Food Bank Association, the Fort McMurray Firefighters Relief Fund, the Borealis Consulting Services and Habitat for Humanity Wood Buffalo. Some funds were also initially donated to the Canadian Red Cross directly by members to help with immediate needs during the evacuation of Fort McMurray. The relief fund was distributed by the CIM Oilsands Branch. Isaac Bussin, the branch’s chairperson, said the board wanted to donate the money to smaller charities that do not have large endowments. “It’s a hard question, but we looked at who needed it the most,” said Bussin. One of those was the Northern Lights Health Foundation, a charity that provides medical services and equipment to the local community. The branch usually raises money for the foundation through its annual golf tournament, but it was cancelled this year due to the wildfires. CIM provided about $31,500 to the foundation, which will go toward purchasing a bronchoscope to detect smoke damage in the airways of affected community members, said Bussin. The Oilsands branch also donated about $38,500 – or roughly one third of the total funds collected – to the Wood Buffalo Food Bank Association. According to Anna Noble, communications and development coordinator at the food bank, three of every four people using the food bank are new users and nearly half of those receiving food are under the age of 18. “I am very proud of how CIM rose to the challenge as a collective,” said CIM executive director Jean Vavrek. “This is the CIM I came to love in the ‘80s when I started to work in the industry, and the CIM that keeps volunteers, members and corporations coming back.” In addition to the money raised by CIM national and its branches, the Canadian Mineral Processors society March/April 2017 • Mars/Avril 2017 | 23

ing the company’s strategy of investing in junior exploration companies. “We’re good at mining, but the exploration game is an entirely different risk profile and an entirely different set of skills,” he said. “Our partnerships with juniors who conduct that exploration are invaluable to us. It feeds our pipeline.” Teck Resources CEO Don Lindsay said it was important to connect with suitable partners in a strengthening, but still volatile, market. During his address to the AME Lunch, he noted that Teck and Goldcorp were developing projects 40 kilometres apart in a 50/50 partnership called NuevaUnión (New Union) in Chile, reducing the capital costs for both companies, streamlining community relationships and reducing the environmental impact. “As an industry, our mindset has to change,” said Lindsay. “If we want to reduce our footprint, working together is the only way to go.”

Mines minister Bill Bennett, together with his opposition critic NDP legislator Doug Donaldson and B.C. Green Party Leader Andrew Weaver, faced tough questions at the B.C. Government-Industry Political Forum. Land access and the public’s trust in its governance were hot topics. Although there was no mention of the former First Nation chief who staked Bennett’s private property in the Kootenays days earlier, the subject of how easy it is to stake land in B.C. did arise. In response to a question from Hereditary Chief Geel (Catherine Blackstock) of the Gitxsan Nation in northwestern B.C., Bennett said the government should communicate more

clearly what staking a claim involves and that it is just the first step, giving permission to the claimant to apply for permits to explore. “The next step is to work with AME to make sure everyone is aware of what it means when you register a claim online,” said Bennett. “You can’t go dig a hole but it gives you the right to apply for a permit to dig a hole, and that process allows for consultation with communities and First Nations.” Held in Vancouver from Jan. 23 to 26, the conference was attended by 5,834 participants from 43 countries, an eight per cent increase from 2016’s – K.

High stakes While First Nations and territorial government negotiate, more than half of Yukon offlimits to prospectors A rift between First Nations groups and the Yukon government has shut down a major swath of the territory to prospecting. At the end of January, the Yukon government announced two staking bans on Kaska territory, a vast area that covers the south eastern corner of the Yukon and extends into British Columbia and the Northwest Territories. The first is a year-long extension of a moratorium that covers the traditional territory of the Ross River Dena Council, who claim a 63,000-squarekilometre parcel of land. The second – which is set to expire at the end of April – covers territory claimed by the Liard and Kaska Dena Council, whose land sit adjacent to the Ross River territory and encompasses the Watson Lake mining district. The bans only cover exploration and do not affect current projects. The land rights battle stems back to a 2012 Yukon provincial court case brought by the Ross River Dena Council – one of three Yukon First Nations who have never signed a treaty with the Yukon government. The decision

obliges the government to “consult and accommodate” the First Nation when it comes to mineral exploration on its traditional territory. (Following the decision, the Kaska Dena Council and Liard First Nation effectively won the same rights when the Yukon government signed two similar mineral agreements.) In 2015, all parties – the Yukon government, the Kaska Dena Council,

and the Liard First Nation – agreed to negotiate a deal. But according to the Yukon government, which says multiple First Nations’ overlapping claims preclude an easy solution, talks broke down in January. According to Dave Porter, lead council for the Kaska Dena Council and Liard First Nation, the Kaska feel that “the process of free entry staking is a direct violation” of section 35 of the March/April 2017 • Mars/Avril 2017 | 25

agree to a temporary lift of the ban – as long as they feel confident that the Yukon government is serious about negotiations. Negotiations, said Porter, broke down because government negotiators

were not given the power to conclude a deal by government leadership. “It came down to a lack of mandate for the negotiators,” explained Porter. “Given their mandate, we could not see our way to an agreement.” In November the Yukon government changed hands for the first time in 14 years, and Porter said he is heartened by the signals the new Liberal government has sent when it comes to its relationship with First Nations. “All of the indicators from the new government have been positive – but we’re still waiting for them to contact us and let us know they’re ready to negotiate,” said Porter, who noted that the three-month deadline on the second ban is fast approaching. “From my perspective the most practical way to go forward is for the Yukon government and the Kaska to sit down and reach an understanding

Canadian constitution, which affirms and recognizes the existence of indigenous rights. Over the years, the courts have been defining precisely what those rights involve. And the thrust of recent decisions – including the 2014’s Tsilhqot’in decision – have swung the pendulum, giving First Nations more power in determining the outcome of development projects on their traditional territory. Free entry staking, Porter went on, “creates a third party interest” that affects aboriginal title, and at a minimum “triggers a duty to consult and accommodate.” In total, the Kaska staking bans cover 23 per cent of the Yukon. With known zinc and tungsten deposits, the affected area is mineral rich. Noting that many prospectors are First Nations and that the Kaska are not averse to mining, Porter said that the Kaska Dena Council is willing to

developments to resume the negotiations,” said Porter, who added that if an agreement is not struck and the Yukon government does not adhere to the court ruling to “consult and accommodate,” his clients will be forced to pursue litigation – a process that could halt staking indefinitely. According to Yukon energy, mines and resources minister Ranj Pillai, an interim agreement with Liard First Nation and the Kaska Dena Council is a priority of his government. In the long term, he says he is aiming to strike a deal that balances the interests of Kaska, industry and Yukoners. While he said he is hopeful he will make one, he “is not going to make any promises that we’re going to fix this in 90 days. I hope it happens, but I’m not going lead anyone on.” The challenges, he said, boil down to three key issues: identifying traditional territory, resolving overlapping territorial claims among First Nations and categorizing the land (figuring out who has the rights to what). According to an interview Pillai gave to the CBC in early February, a number of different groups with overlapping claims are affected by any decisions the government makes and the Kaska have been resolute in their assertion that they have title over 100 per cent of their traditional territory. When it comes to the future of the territory, however, Pillai is adamant that mining will continue to play a central role in the economy and that the Yukon is poised to enter “the most robust time we’ve seen in history when it comes to mining.” While relations between government and Kaska face challenges, both Pillai and Porter said the Kaska are working with miners to bring existing projects to fruition. Golden Predator, a junior company that has been working with the Kaska to get its 3 Aces project off the ground, has proven itself to be “honest and open” and willing to “put a fair share of wealth on the table,” said Porter. But for prospectors like Ron Berdahl, the bans are a deep source of frustration. Combined with pre-exist-

ing staking bans, 52 per cent of the Yukon is currently off limits to staking. The Ross River staking ban extension, said Berdahl – who serves as president of the Yukon Prospectors Association – simply represents “one more domino in a long line of dominos that have already fallen.” While

Berdahl has held properties within the Ross River area since the 1980s, he has not been able to explore them since the court decision. For Berdahl, the long term prospects for prospecting in the territory look good – but when it comes to the near term, he is less optimistic.

The list honours and recognizes the mine finders and developers of the Canadian industry across five nomination categories, from daring exploration to technical achievements. “The Canadian Mining Hall of Fame is proud to honour these five outstanding individuals for their significant contributions to the mining industry, both in Canada and around the world,” said Bill Roscoe, chair of the Hall of Fame, in a statement. “These individuals have played a pivotal role in the development and growth of the sector in Canada and around the world.” Carter, the former COO of Syncrude, is an oil sands leader who helped develop the fledgling industry and the frontier town of Fort McMurray. McEwen, chairman and chief owner of McEwen Mining, is a mining entrepreneur best known for transforming Goldcorp from a holding company into a gold-mining powerhouse and revitalizing Ontario’s Red Lake mine. 28 | CIM Magazine | Vol. 12, No. 2

McLeod, a miner and founder of the Northair Group, developed the Brandywine and Summit gold mines in British Columbia, and made high-grade gold discoveries at the Brucejack project. Vaughan, a corporate social responsibility advocate, is one of the best known mining lawyers in the world, who helped advance the successful globalization of the Canadian mining industry. Zigarlick, best known for developing Echo Bay Mines Ltd., conceived and led the construction of the world’s largest winter road to service the remote Lupin gold mine 400 kilometres northeast of Yellowknife. He passed away in 2011 at the age of 74. This year’s induction ceremony was held for the first time at the Toronto Convention Centre before a sell-out crowd of about 1,000 guests. As in previous years, philanthropist and FrancoNevada chairman Pierre Lassonde hosted the dinner. A total of 177 industry professionals have been inducted into the hall of fame since it was created in 1988. The induction ceremony was supported by diamond sponsor Hecla; dinner wine sponsor Hatch; VIP reception sponsor SNC-Lavalin, and platinum sponsors Barrick Gold, Franco Nevada, Magris, Syncrude Canada and Yamana Gold. – D.

Reconnecting with experience can strengthen the mining sector By Kirk Rodgers

ver the many years that I have been involved in the mining industry, I have come to see that one of the key strengths of First Nations communities is their respect and reliance on advice from their elders. It is an idea that the mining sector might benefit from. In First Nations communities, elders are people who have achieved significant wisdom, often by virtue of their age. Among the many roles elders take on in their community is the sharing of their experience by providing valuable advice. Elders provide a continuity of knowledge, helping younger generations of leaders learn what worked in the past and what did not. Contrast that with the mining sector, where many of the older, experienced people leave the business, often as early as their 50s but always by their mid-60s. At the same time, the mining industry is suffering through a significant demographic shift where the number of young to mid-level personnel is significantly lower than in past decades. It is true that this younger generation has computer-based skills that improve their efficiency. New tools help them do the work in a fraction of the time and with much less staff than the generation that started out using only calculators and slide rules. However, technology alone is not enough to successfully develop a mining project. Consider a common task in a mining company – the pre-feasibility study of an undeveloped mineral deposit. In the 1970s, such a study might have needed a team of 20 engineers and geologists, and six to nine months to complete. In 2017, the work could probably be completed with a team of five engineers and geol-

ogists, working for about three months. The difference is the result of the high-speed tools that automate repetitive tasks. But a key difference is that the 1970s team would probably have had about 10 people over the age of 40. These would have been people who had built their careers working in mines. They would have had a keen understanding of what would work in

is value in this experience, that it should be used and that there is a need for some procedure to tap into it. It could offer a range of expertise – such as open pit, underground, heap leach, remote sites, operations in Africa or Latin America, or the special needs of uranium mining. On the elders’ side, they can work when and how much they want, according to terms agreed upon with

“Technology alone is not enough to successfully develop a mining project.”

the real world of mining, rather than what looked good on paper (or a computer screen). In 2017, the pre-feasibility team may have one person over 40. The entire team’s experience may be based primarily on managing technological tools rather than the actual conditions that the project will encounter when constructed. So how can the mining sector get the best of both worlds? The answer lies in bringing the older and more experienced people back in contact with the mining industry. Then, by working with the strengths and preferences of both groups, companies can get the best results from the new tools that are being employed. We might call it an “agency of elders” – a group of experienced mining professionals who are retired or semiretired, but who still love mining and are interested in staying involved and sharing their wisdom. This agency need not be formal or official, and maybe it is just a recognition by the mining industry that there

the mining or engineering company. The benefit for the company is that it gets the wisdom of their experience. Think of it like a sober second opinion. Investors and owners will certainly appreciate this being available and used in important decisions. Many presentations at mining conferences, as well as a few more discussions over a beer, have focused on the aging of the mining workforce, and the loss of all that wisdom. An “agency of elders” is one way to help with that problem, in a way that works for the mining industry as well as the growing community of “elders.” CIM

Millennials in mining: preparing for the next generation of miners By Brandon Gill

n 2011, I entered the Colorado School of Mines (CSM) to study mining engineering. Like everyone else, I was told that as the baby boomer generation started to retire, the mining industry would need a new wave of people to fill the labour void. But during the four years I spent at CSM, a lot changed in the industry. Commodity prices dropped, companies went bankrupt and many of us soon-to-be graduates that once had a lot of confidence in our careers were left wondering how we would find work during one of the worst downturns the industry has ever seen. With the economic downturn, finding a job in mining became a much different – and more difficult – task than it had been even a few years earlier. And even when the industry begins to recover, new waves of miners may be ushered into career paths that are anything but “traditional.” Enter a new kind of worker to the mining industry – the millennial. “Millennial” is the media classification for those of us between the ages of 20 and 36 that sometimes holds a negative connotation. Millennials are often viewed as arrogant, entitled, lazy and immature. It is true that we millennial miners are different than our baby boomer predecessors, but it is not because we are entitled or lazy; rather it is because our world is different and so are our resources. We have grown up with access to knowledge virtually at our fingertips. It is a world where one simple idea going “viral” could launch a massive new company and change the

world. Technology has enabled us to move, learn and act quicker than ever before. The technology developed during our lifetime has changed our world, and now we are here to use that technology to change the mining industry

For example, the summer before graduating I stumbled into an internship (and eventual full-time position) in the financial district of San Francisco with a technology company called Alight that does financial forecasting and scenario planning for top-tier mining companies. It is not exactly how (or where) I thought my career might start when learning about underground mining methods a semester earlier, but it has led to incredible opportunities to use technological knowledge to benefit the industry. As the industry starts to climb out of this recent slump, many believe technology will lead the way, and technologically fluent millennials will be essential to this transformation. For proof of this, we only have to look at one of the most widely known vendors in the mining industry – Caterpillar.

also a tech company, and is probably doing it with a little millennial help. Do not underestimate us for the conveniences we have been afforded; embrace the opportunity this knowledge brings with it. Embrace the fact that because we have always been able to learn anything we want very quickly, we may have new ideas that the industry would have never thought of. Embrace our knowledge the way that we will embrace yours and, together, we can continue to drive our industry (and the technology that will fuel it) forward in the near and distant future. CIM

Frank Poole (far right), senior manager of development and construction at PT Freeport Indonesia’s Deep Mill Level Zone mine, visited Redpath’s operations in North Bay, Ontario, to learn more about its Redbore raisedrill program.

So Poole suggested the Freeport team look at upreaming (or boxholing) the slot raises instead. “Boxhole boring has been around for a long time. I’ve used it a lot in Australia,” he said. “Frank, being a new manager coming to site, as all new managers do, brought his experience level and knowledge,” added Herault. “It was a new set of eyes for us, and a challenge we wanted to achieve.” By 2014, Freeport began discussions with Redpath, which had experience elsewhere with the technology and method, about switching to boxhole raiseboring to ream the drawbell slots at the DMLZ. Initial conversations stalled, said Edwin Hernandez, a senior mining engineer at Redpath, but in 2015 the subject came up again. “I was pretty keen to make the change,” noted Poole. “We presented the different machines we had to do upreaming,” said Hernandez. But to replace the 2.1-metre diameter, 12 to 20-metre long Alimak raises, Freeport required a larger reamer head than had ever been used on a boxhole machine before. “At that point, we only had up to 1.5-metre diameter reamer heads,” Hernandez explained. “Freeport wanted to find out if we could do 1.8 metres.” Freeport issued a request for a proposal, specifying the requirements that contractors would have to meet. Redpath proposed a re-engineered design to its Redbore 50 line of drills – the Redbore 50X – with a 1.8-metre reamer head and a reengineered deflector, which offers a high level of protection for the crew. Included in the RFP was a stipulation calling for an on-site trial of the new machine to prove its capabilities.

On trial A four-hole trial was planned for June and July 2016. The trial was awarded to Redpath due to its quick response time to fulfill Freeport’s requirement. There were teething problems, however. The machine’s water requirements on site, both for reaming and for dust control, came as something of a surprise, said Hernandez. And some of the older drawbell development sites were a bit too tight for the new machine, so the floors had to be lowered to accommodate the 50X, March/April 2017 • Mars/Avril 2017 | 33

RESOURCES

explained Larry Hill, a technical expert for Freeport at the DMLZ. “But overall, there is not really a huge change,” Hill said. “It’s basically like the boxhole rig replaces the Alimak. It is still the same sort of process.” Despite the early issues, the new method was an immediate hit at Freeport. The smooth, undamaged-by-blasting walls meant that collaring the raises was easier. It also meant a lower chance of rocks coming loose and falling. However, said Hill, “The biggest thing that we have seen has been our speed of drilling around the raise itself. We have saved so much time in not having to do re-drills and realignments. It has made life a lot easier. The drill comes in, drills and goes. It doesn’t have to stay there an extra two or three shifts trying to drill around the raise.” By comparison, Poole said, “The Alimak takes about twice the time.” The limiting factor during the trial was often the readiness of site preparations. Reaming the entire raise also allowed scheduling efficiencies. “With drill and blast methods, the policies and procedures in the DMLZ are such that you are only allowed to blast during the scheduled blasting times,” explained Herault. “The round may be completely drilled off, but you still need to wait four or five hours before you blast. That becomes non-effective time. With a boxhole machine, it is effective from the moment the men show up until the end of the shift when they leave. You’re not held back by scheduled blasting times to get your advances.” The Redpath machines have another productivity-enhancing feature, too. The company is preparing to introduce remote drilling at the DMLZ this year, which will allow reaming work to continue even during frequent seismic activity, when workers must be removed to a safe zone underground.

The four trial raises were completed ahead of schedule, with no safety incidents. Freeport was so impressed with the performance of the re-engineered Redbore 50X that the machine simply continued working after it finished the trial. Freeport purchased a second unit, which arrived on site at the beginning of February. “Once we get right into it at the DMLZ,” said Poole, “we could possibly have three rigs working.” And, he added, the 160,000 tonne-per-day Grasberg Block Cave mine currently under development nearby could employ another five boxhole machines to help develop its nearly 2,400 drawbells. “The whole process went very smoothly,” said Poole. “Redpath got in their raisebore experts from Australia, brought some specialized boxhole people from Canada, and they put it together very well.” The boxhole machine may present more upfront cost than an MRC unit, admitted Herault. But, he said, the lower labour requirements, inherent safety advantages and productivity gains work in its favour, especially over the 20-year operational life of the DMLZ. “It’s so much easier to drill the holes exactly where you want them,” Poole agreed. “Overall, we are saving a lot of money and minimizing risk.” With success at 1.8 metres, the evolution of upreaming technology continues, said Hernandez. “Redpath has already manufactured two new drills, the Redbore 60, for two-metre upreaming for projects in Chile.” CIM

Digging deeper for answers The challenge of rock stress in the dawning age of ultra-deep mining By Christopher Pollon

reland-born Damien Duff spends a lot of time thinking about how to make ultra-deep mines – defined roughly as mining below 2,500 metres (8,000 feet) – safer for people and more economic for companies. His deep mining research at the Centre for Excellence in Mining Innovation (CEMI), where he is a vice-president in charge of geosciences and geotechnical R&D, took on a new intensity in 2013 with the creation of the federally funded and industry-supported Ultra-Deep Mining Network (UDMN), which continues to focus on overcoming the biggest challenges inherent in the future trend of digging ever deeper.

CIM: What was your career path leading to your work with UDMN? Duff: I was born and raised in Dublin, Ireland. I went to Laurentian University in 1979 to do my post-graduate degree in geology, largely because it’s located in the heart of Canada’s 36 | CIM Magazine | Vol. 12, No. 2

mining industry, and I wanted to learn something about the hard rock mining business. I started my first job in Timmins in 1981 for Pamour Porcupine Mines in underground mine geology roles there as well as in open pits, but transitioned into mine site exploration. By 1989 I moved to Falconbridge in Timmins and stayed with them through their transition to Xstrata, and finally Glencore in 2014.

CIM: How did you get interested in ultra-deep mining? Duff: I worked at the Kidd mine in Timmins at a time when they constructed their now-famous ultra-deep extension to depth – the Mine D project. Before, Kidd reached 6,800 feet below surface, and now it’s about 9,800 feet. I participated in the feasibility study and initial development work for the deep ore body, and it became apparent that there were very significant challenges associated with digging deeper and that research gaps

underground mining existed. I joined CEMI in 2008. The UDMN did not come around until 2013, but its time had come, let’s put it that way.

CIM: What are the challenges associated with digging ultra-deep mines? Duff: The first and foremost challenge is dealing with rock stress and how that can impact human safety, productivity and mine economics. Stress is an unseen force that exists in rocks (both shallow and deep) throughout the world, largely because of plate tectonics or continental drift. In a mine, there’s the sheer weight of the overlying rock, which increases the stress on any opening the deeper you dig. There’s also horizontal stress, which in places like Sudbury, for reasons not entirely clear, increases substantially at different depths and at different locations. Around Sudbury and Timmins, for example, the horizontal stress below 1,000 to 1,500 m markedly increases in intensity, whereas in Saskatchewan, for example, it does so at substantially shallower depths. But in this part of the world, below 1,500 m, where horizontal stress increases, we can expect an increase in the rate at which the rock fails as we tunnel. Furthermore, that rock is now behaving in a much more violent way when it fails, compared to failures at shallower depths.

CIM: So how are you working to manage these kinds of impacts? Duff: We have six projects focused on reducing the risk associated with stress at depth, looking at unconventional ways to measure rock stress, ways to assess geotechnical hazard, and finally, proactive actions we can take to modify rock mass behaviour in advance of mining. In each of these areas, we are focused on trying to figure out easier, more cost-effective and quicker ways to know what the level of stress is in our underground mines at all times. UDMN is putting money largely into small- to medium-sized enterprises (SME), companies that from time to time will work with university researchers, but are being encouraged to produce commercializable products at the end of their projects with UDMN.

CIM: What is promising in terms of trying to measure deep mine stress, its magnitude and where it is coming from? Duff: ESG Solutions is an SME based in Kingston, Ontario, which is looking at micro-seismic data that we already collect in most mines, but in a way that allows the evaluation of the location and magnitude of micro-seismic events caused by stress changes. By carefully analysing where tremors and vibrations occur in the mine, it’s possible to calculate the orientation of the principal stresses. Being aware of this can inform how we both operate and design our mines in the future. In another project, the Institute of Mine Seismology (IMS) is looking beyond passive micro-seismic data in a mine. While ESG is listening to the vibrations in the rocks in the hopes of understanding the changing stress environment, IMS is installing an active seismic source of vibration with a specific signal, which can be readily separated and identified from all

these other man-made vibrations in the mine. So it’s effectively a hammer they are putting into the mine, with a precisely known signal and location, which can be heard by a microseismic array employed underground. By listening to the changes occurring to the signal and assessing the clarity by which it can be heard, they can determine whether there are stress changes occurring in the rock mass in response to mining, and where they are occurring.

CIM: How can this information be used to inform how we mine? Duff: The two different approaches are focused on better understanding how stress is changing underground as we mine. When we can understand that, we can better design our mines and select the appropriate ground-support strategies to lower the risk of disruptions. Better designed mines might mean our openings are a certain size and even constrained in size below a certain depth. And furthermore, those openings might ideally only be driven in a certain direction, at a certain rate.

CIM: What proactive ways have you looked at to dissipate rock stress in advance of ultra-deep mining? Duff: There is a project being undertaken involving a major mining company’s operation in Sudbury, working with MIRARCO, looking at hydraulic fracturing to precondition the rock mass at a block scale by first micro-damaging it through the creation of cracks. After fracturing, it is filled with a series of micro-cracks and fractures, all of which interact with one another in such a way that stress is not able to build up to any extent and thus violently unpredictable behaviour is avoided. That means we are not forced to wait for one big failure, which otherwise could happen without this preconditioning. At a drift scale, the Itasca Consulting Group is also working to optimize current preconditioning approaches.

CIM: In the bigger picture, will digging deeper mines be a trend for the future as a result of having already mined resources closest to the surface? Is this a trend we will see more of in the decades to come? Duff: It’s my view that it is a trend we will see more and more of. Most if not all of our established mining camps, at least in this part of the world, whether it’s Timmins, Sudbury, or many others, are all 100 years old, or close to that. This means that most of the possible near-surface ore body discoveries have likely been done and most of the future potential for new ore bodies likely lies at depth. Because established camps are so well explored, much of the future potential lies in figuring out a way to mine the known ore bodies at greater depths than we are currently capable of mining them. In many cases, these ore bodies are open to extreme depth – for example, at Kidd mine, they are only mining above 9,800 feet, but there’s a borehole in the ore body that goes down past 10,000 feet. Society needs the metals and we’ve got the resources at depth. Now we just need to figure out how to mine them safely and economically. CIM March/April 2017 • Mars/Avril 2017 | 37

Economic and environmental concerns have miners zeroing in on how much energy their operations require, how much is wasted and how those concerns are changing the thinking on measuring performance

By Eavan Moore

The Eleonore mine in the sub-Arctic of Quebec is just one of ten that Goldcorp operates across the Americas, all of which have energy managers devoted to scrutinizing energy consumption on site.

Energy management is becoming increasingly important for mine sites grappling with rising energy costs and greenhouse gas (GHG) emissions. According to data from Natural Resources Canada, electricity and fuel costs in the hard rock Canadian mining sector increased 20 per cent between 2012 and 2014, rising from 15 per cent of production costs to 16.7 per cent. Although it can take numerous possible forms, an effective strategy requires an organized approach with toplevel support, flexibility on site and widespread buy-in. The pressure of energy costs – combined with environmental and health and safety concerns – sets a complex task for Goldcorp, which has ten operating mines and three development projects across the Americas. “We’re seeing increases in the cost of energy,” said John Mullally, director of government relations and energy at Goldcorp, “and we’re investing today for mines that will be operating 10 and 12 years from now. There are costs today, and risks that those costs five years, seven years, from now could be significantly more.” Combined with the health consequences of diesel use and environmental GHG issues, in the end, “all those costs end up impacting both on the productivity and the sustainability of business.” In 2012, Goldcorp set overarching corporate objectives for the following five years on renewable energy (source five per cent of energy from renewable sources), GHG reductions (cut by 20 per cent), and energy efficiency (increase by 15 per cent). In addition, individual mine sites set their own goals. The Musselwhite mine in Ontario focused on optimizing dewatering, improving ventilation and controlling peak electrical demand. At the Peñasquito mine in Mexico, comminution gained efficiency with the installation of a high-pressure grinding roll (HPGR) and blasting techniques that improved the mill feed. “These recommendations come from the subject matter experts, and in this case the subject matter expert is the dedicated energy manager [at each site],” said Mullally. “The creation of a dedicated energy manager has meant that there’s a central point person who’s accountable for energy consumption, which means that we’ve got better oversight and better traction with respect to energy conservation.” March/April 2017 • Mars/Avril 2017 | 39

The ventilation on demand system at Eleonore includes personnel tracking using hard hats equipped with RFID tags to ensure ventilation is concentrated only where it is required.

Culture of conservation The energy manager brings energy awareness to bear on every area of the business, large and small. “Halogen lights will consume ten times the power of an LED light,” said Mullally. “In a facility that’s as energy-intensive as a mine facility, that’s a difference of hundreds of thousands of dollars a year.” Just as importantly, the energy manager at a site is also responsible for creating a culture of energy awareness among employees. Andrew Cooper, energy specialist at New Gold’s New Afton mine in British Columbia, thinks this aspect of energy management is underrated. “We’re going through a phase where people are focused on the sexy side of energy management,” he said. “They look at renewables, and they look at new technology and big data and all of this stuff that’s out there now.” But some of the biggest savings come from basic conservation habits – things as simple as deciding to turn on the cold water faucet instead of the hot. “The other stuff’s important, don’t get me wrong, but I think people are losing touch with the basics,” he said. “They substitute their current power with renewable power and then they still waste it.” Energy awareness was a major part of New Afton’s ISO 50001 implementation, which started in 2013 and culminated 40 | CIM Magazine | Vol. 12, No. 2

in certification for the international energy management standard in 2014. Since then, the time spent on generating energy awareness has barely receded, according to Cooper. “Every year there’s different groups of people who need different training, different updates in what they’re doing. So it doesn’t really diminish. And we find we have to maintain the same sort of focus and try and come up with new and exciting things to keep it interesting.”

“It’s looking at what your energy dollar buys you, not how much work your energy does.”

One fun awareness campaign held at New Afton in 2016 was suggested by one of the energy team members. FLIR Systems makes a thermal imaging device that can plug into the bottom of a smartphone. “We bought a whole bunch of these, and we set up a big awareness cam– Mary Stewart on shifting paign and encouraged people the focus from efficiency to borrow them and check to energy productivity what’s losing energy in their home,” said Cooper. “Their windows, their doors, their hot-water heaters, their furnaces, etc.” Employees were able to share these pictures with one another over SharePoint. “That’s quite an exciting campaign, and we’d like to believe that it’s helping people create awareness of energy at home, which rolls over into the workplace.” When employees get involved, they start coming up with ideas. A mechanic at New Afton suggested adjusting compressor set points, which resulted in a 0.9-gigawatt (GW) annual energy saving. “That was a zero-cost thing that one of the employees undertook himself,” said Cooper. Compressed air management is low-hanging fruit, an obvious source of energy wastage with low-capital solutions. When Goldcorp campaigned to reduce waste from worn-out components on air compressors at its Red Lake mine, the main challenge was getting everyone aware and proactive. “Even if it’s cheap in terms of capital, it requires a lot of coordination,” said Mullally. “And the energy manager is responsible for rolling out the initiative, communicating, following up with respect to results, and in some cases, awarding and incentivizing these types of things with prizes.” 42 | CIM Magazine | Vol. 12, No. 2

At the other end of the cost spectrum, Ventilation on Demand (VOD) requires major investments in systems and software, but brings significant returns by turning on fans only when they are needed. “We spend $25 million per year to ventilate our underground mines in Ontario,” said Mullally. “That’s a serious expense. Fifty per cent of our electricity consumption at our mine sites in Ontario is from ventilation. So any initiative that can address the consumption of electricity through ventilation is a big win.” Goldcorp’s Éléonore mine was built with VOD and the same is planned for its Borden Lake mine. The capital-intensive projects, however effective, are out of reach for many mines. Mary Stewart, executive director of the Australian consultancy Energetics, said that access to capital was a key limitation for smaller companies. “Some of them are not able to afford the big solutions,” she said. Ironically, Stewart remarked that it is smaller companies that are more likely to innovate, yet have the least capital available to do so.

Renewable energy Renewable generation projects have gained traction globally. Installing renewables helps hedge against future energy costs and ensure supply in jurisdictions with no access to the grid. In Canada’s Far North, a wind farm at the Diavik diamond mine has been leading the way since 2012, offsetting the demand for diesel fuel. Glencore also installed a single wind turbine at its Raglan nickel mine in 2016. That same year, Sandfire Resources installed a solar power facility at its remote DeGrussa copper-gold mine in Western Australia. The $40 million project will supply about 20 per cent of the mine’s annual power, supplementing the existing diesel generating station.

“With battery prices coming down, those hybrid systems are becoming very competitive with both off- and on-grid energy sources,” said Stewart. Moreover, Stewart noted, “Once you pay off your renewables, you essentially have free energy. That means that you can extend your mine life because you have access to very cheap energy at a point in time where your ore grade is low, and you can still afford to get that ore to the surface and process it.”

Peak problems Even for a mine that is on the grid, having a self-contained and cost-effective source of energy could address a new challenge: peak-based pricing. According to Stewart, electricity markets have shifted from usage charges to network capacity charges. “Capacity-based pricing is encoded for the east coast market in Australia,” she said. “This is the majority of grid-connected electricity in Australia and includes all generators, network operators and retailers. Capacity-based pricing is also present in Canada, the United States, and in Europe to different extents and as a function of the market.” In this pricing regime, a mine is charged for the capacity required to deliver its peak usage. The cost-cutting strategies appropriate for controlling peaks are different from general usage. For example, peak use often occurs when large equipment is started up. A mine trying to minimize its peak charges would schedule equipment startup for times when it is using less energy elsewhere. It might also put in equipment with variable-speed drives or install soft-start mechanisms on motors. “More sophisticated approaches include site flux analyses and ensuring that your site load is well-managed and not peaky,” she said. Site managers may not realize this is happening because contracts are typically not negotiated on site. But the finer details and complexities of electricity contracts heavily inform Stewart’s conversations with major ASX-listed companies that form Energetics’ mining client base. Energy conservation goals are often framed in terms of the energy efficiency of processes or equipment, where the metric is something like “kilowatt-hours (kWh) per tonne of throughput.” Stewart brings a different suggestion to her clients: energy productivity. “What we talk about is dollar of energy invested per dollar of product-value created,” she said. “And that starts giving you a different way of looking at things.” Stewart said there is a movement underway to look at energy saving in these terms in the United States, Canada, Australia, and most recently in South America. “Talking classical energy efficiency is going to become less important because the focus should be on what you’re spending the money on,” she said, “because the charges are going to look different. It’s looking at what your energy dollar buys you, not how much work your energy does.” Energy pricing schemes can take up quite a lot of the energy specialists’ time if they are complex. Ontario’s global adjustment program effectively charges Goldcorp’s mines extra for their usage on the five days out of the year when province-

wide usage peaks. Since it is impossible to be sure that an anticipated high-usage day will turn out to be one of the top five, mines that try to control this aspect of their energy costs essentially have to gamble by cutting production on what they think will be peak days. But Ontario’s pricing scheme can be complicated. “In B.C. it’s pretty straightforward,” said Cooper. “The past three or four years, we’ve actually known what our increases are going to be in advance, which has allowed us to budget for that and we don’t have the global adjustment challenge.” Cooper said that New Afton’s electricity provider, BC Hydro, does calculate maximum demand, but that it is not adversely affected by motor startups and that energy reduction is not aimed specifically at reducing peaky behaviour. New Afton’s energy conservation goals are simple as well. Instead of measuring its energy savings in terms of efficiency or productivity, New Afton picked a method that seemed simple and achievable: take the total energy consumption from the previous year, calculate a percentage of that amount, and make that the goal for next year. For example, in 2016, New Afton looked back at its 2015 consumption in kWh or gigajoules, calculated one per cent of that total number, and planned to implement projects that would reduce its 2017 energy consumption by that number – 2.74 gigawatt hours (GWh). Even if the mine’s total energy consumption goes up that year, due to throughput increases for example, the mine would still have realized energy savings from the projects implemented. In 2016, New Afton aimed to cut 2.54 GWh and actually saved 4.5 GWh. “It’s easy to measure, easy to quantify, and we can FURTHER achieve it,” said Cooper. “It’s a READING very simple way of doing it. And it works.” From CIM Journal Finding meaningful but realisEnabling progressive tic goals can be tricky in a continenergy management uously expanding and changing practice in minerals operations mine. “Mines get deeper, rock By Dean Millar, Michelle characteristics change, ore bodies Levesque, Glenn Lyle become more or less complex; and Keith Bullock working out how you are going to predict improvement relative to From CIM Magazine [your baseline] is very compliAir supply on cated,” said Stewart. “So a simple demand: New ventilation value that unites everyone is very technology provides useful.” airflow when and She added that some mining where it is needed By Krystyna Lagowski companies are looking at shaping their GHG reductions to the interCertifiable gains in nationally targeted two-degree efficiency: New Afton the first ceiling on global temperature mine in North increase. “It requires significant America to meet the and absolute emissions reducISO 50001 energy management tions,” she said.

MILLING AND GRINDING

Field tested Case studies in the hardware and software behind improved milling plant performance

By Ian Ewing

The two-mass vibrating screen from General Kinematics, shown here being installed in China, is designed to handle higher thoughput without needing more power or space.

arger mines, lower commodity prices, and new technologies all put pressure on mill operators to keep up. Controlling what goes into the plant, measuring what comes out and adjusting on the fly have all yielded performance improvements in operating mills thanks to their precision and efficiency.

Beyond brute force As mines and mills get larger, so must the material handling and processing equipment. General Kinematics provides a solution to the problem of size limits in brute-force vibrating screens. Their two-mass vibrating screens, which use a second mass set on reactor springs that moves in the opposite direction as the screen below, are designed to have a natural frequency near the frequency at which they operate. Doing so allows their screens to use smaller motors and exciters â&#x20AC;&#x201C; often just a third of the size and power of an equivalent sized brute-force screen, leading to drastically lower energy consumption.

MILLING AND GRINDING

“There are limits to how high you can go with a bruteforce drive. If we’re doing the same amount of work with a third of the horsepower and a third of the drive, in theory we can get up to three times the size,” said Steve Massman, technical director at General Kinematics. “Lower horsepower also means smaller motors, which means easier and less costly replacement of the motors and drive components.” Massman and Edward Wipf, president of EdRockMan IV, consultants who represent General Kinematics in the mining industry, spoke to CIM Magazine about the equipment. “In one of our installations, a coal plant in Australia,” Wipf said, “the screen was able to do up to 40 per cent higher throughput in the same footprint as the original brute-force screen, at the same screen efficiency.” The screens are also better equipped to handle material surges. Adding material to the screen increases the effective weight of the system, moving the natural frequency of the screen closer to its operating speed. That causes the stroke to actually increase under load, rather than bogging down. “By divorcing the motors from the body that is handling the material, impact forces on the motors are lower, too,” said Massman. This increases the life of the motors and drives. The opposing motion of the screen and the mass also decreases the live load transmitted to the foundation. “In a normal screen, there’s the weight of the screen, but also 150 to 350 per cent extra loading due to the dynamic forces that go into the foundation,” noted Wipf. “Here it’s only the static weight plus about 25 per cent.” Lower foundation construction costs can offset the slight price premium of two-mass screens, which run about 1 to 1.2 times the cost of a single-mass screen with the same screen area. “They can be very comparable in price,” said Wipf, “because the two-mass screen technology can give you 20 to 40 per cent higher throughput in the same floor space. You’ll also be saving a lot on the energy, on the screen media, and on the maintenance.” As operators require ever larger throughputs, General Kinematics is currently constructing their largest version yet, with a screen measuring 5.3 metres wide by 7.3 metres long. They claim it is the largest vibrating screen in existence anywhere. The modular design, however, means that the larger scale does not present outsized logistical challenges.

Predictive control More data and better equipment are only as good as the people and algorithms controlling the process. Honeywell’s multivariable predictive control technology (MPC) promises to operate a process closer to its limits, maximizing capacity or recovery as desired by the operator. The controller takes historical data from the process and creates a model that correlates the various parameters – generally 10-15 control variables and six to eight outputs in a grinding circuit, but up to 80 inputs and 20-30 outputs in other processes – allowing the effects of ore and set-point changes to be predicted.

| technology

Although it is relatively new to larger Canadian grinding and flotation systems, Honeywell’s MPC has been installed in over 100 grinding circuits worldwide since 1997, as well as in other areas of mineral processing, petroleum refineries, and other industrial plants. In the average milling application, MPC has been in use for eight years at a utilization rate north of 90 per cent, noted Bob Jonas, Honeywell Process Solutions’ mining and metals business development manager. “MPC was implemented in the grinding circuit at Agnico Eagle’s Goldex mine in June 2015, controlling the SAG mill and classification. Later the ball mill and ore blending was added, in total, taking in ten inputs (measured values) and controlling nine outputs,”said Jonas. “The system is used over 90 per cent of time, resulting in 35 per cent fewer setpoint changes required by operator, increase in gold recovery of 0.85 per cent, and,” he added, “the system paid for itself within a year,” referring to recently published results by Agnico Eagle. At Goldex, the MPC was implemented over eight days. During the first four-day visit, during which time its historical process data was collected to automatically learn the various interactions. “When the ore feed changes, how does that affect the power of the mill?” asked Jonas. “The system identifies all those interactions automatically, in a very precise way. Then it tells the engineer any areas where it was unable to establish relationships, identifying a need to fix instrumentation or need to get better data.” During the second site visit at Goldex, the operator made some set-point adjustments to provide data to the MPC to learn the missing relationships, and then the MPC controller was commissioned. In a milling process, Honeywell typically optimizes the algorithm to increase ore tonnage using a simple principle. “When things are stable, when load, power and other limits are not exceeded, add ore,” said Jonas. “Customers will regularly see two to six per cent higher throughput, and sometimes as high as 10 to 20 per cent higher using predictive control.” At Goldex, however, challenged by lack of ore, the MPC is instead optimized to stabilize the process and get a more uniform grind size, helping optimize downstream processes like recovery in the flotation cells. “The MPC, using predictive control, knows very precisely the effect of each parameter. It will tend to ramp the changes in a very smooth manner, in the course of just a couple minutes. It does this in a responsive way to maintain control, but also in a stabilizing manner that contributes to a more uniform grind size.” By contrast, Jonas said, “a normal controller uses only feedback. It makes a change, and then waits to see how that affects the other parameters of the system. If there is a delay – it can take 10 to 30 minutes to see the full effect of a change – the controller can’t make all the desired changes at once.” Because of the risk of upsetting the process if it overshoots, a normal controller is very conservative when making changes and does not do a good job of stabilizing, he said.

MILLING AND GRINDING

Thermo Fisher Scientific’s particle size monitor PSM-400MPX is deployed at Agnico Eagle’s Meadowbank mill.

Particle size analysis Agnico Eagle has improved throughput in the grinding circuit at its Meadowbank mine by collecting more data on the size of the particles leaving their mill. Frequent changes in hardness caused by varying ore types makes optimizing recovery challenging. Thermo Fisher Scientific’s PSM400MPX on-line ultrasonic particle size analyzer helps Agnico stay within limits. Particle size analysis at Meadowbank reduced grind size to 4.4 microns, increased mill throughput by nearly seven tonnes per hour, and improved recovery at the mine by 0.64 per cent, to the tune of an extra 249 ounces of gold per month, according to a paper presented at the 49th annual Canadian Mineral Processors Conference (CMP 2017). “When metal prices are low and operators are struggling to make profit, their attention turns back to being better operators rather than just pushing throughput,” said Tom Strombotne, global product manager for minerals at Thermo Fisher. “On-line particle size analysis can be used by operators to establish that they’re achieving the target grind in realtime, or to maximize throughput through the mill while keeping the grind below some absolute maximum size for downstream processes.” Currently, this fourth-generation particle size monitor can measure five discrete particle size fractions over the full particle size distribution, as well as the per cent solids in the slurry. Although the product has been on the market for nearly ten years, this latest version offers Ethernet connectivity, an improvement on older analog systems. In the last five to eight years, added Strombotne, the company has paired the PSM with a SamStat multi-stage, static metallurgical

accounting station. The SamStat has a primary sampling stage feeding a secondary sampling stage, which then provides a smaller, continuously flowing sampling zone from which the PSM can acquire a representative sample. “That’s one innovation that has made the technology amenable to the way higher-throughput modern plants are designed,” said Strombotne. But the benefits do not happen by accident, he cautioned. “If you went around the globe and visited all the plants that have particle size analyzers, you would find a wide distribution of how effectively they are employed,” Strombotne said. At Meadowbank, emphasizing regular maintenance and cleaning of the PSM-400 and its Samstat-20 flow sampler corrected a scaling problem and ensured that the mine saw a rapid payback on the roughly $200,000 piece of equipment. Thermo Fisher expects to work with operators to enhance the product further. “The future is bright in terms of exploiting the science of ultrasonic scattering to produce continuous particle size distribution on-line that doesn’t require calibrating against discrete sieves,” said Strombotne. Though mill operators and metallurgists say they would like that information, they are not yet sure how they would use it to make money. “It’s one thing to have the technological capability, but we have to figure out ways in which the information can be exploited.” CIM Further reading Information on all of these technologies can be found within the proceedings of the 49th annual Canadian Mineral Processors Conference available at cmpsoc.ca March/April 2017 • Mars/Avril 2017 | 46

mot du président

Compte rendu du Ralliement congrès de la PDAC des mineurs En route vers Toronto pour assister au dernier congrès de la Prospectors and Developers Association of Canada (PDAC, l’association canadienne des prospecteurs et entrepreneurs), j’ai contacté un ami géologue pour lui demander que l’on essaie de trouver un moment, ne serait-ce que quelques minutes, pour se voir. Il travaille régulièrement sur des projets menés au Canada, en Amérique latine et en Afrique du Nord, et est pour moi un baromètre de la santé du secteur de l’exploration. Étant tous deux pères de jeunes enfants, je m’inquiète pour lui sachant que le travail se fait rare dans ce domaine et qu’à mes questions, il se contente de répondre d’un hochement de tête et change rapidement de sujet. J’ai alors pensé qu’en le contactant suffisamment à l’avance, j’aurais la possibilité d’en apprendre un peu plus sur les travaux qu’il mène dans le nord du Québec avec sa société récemment créée. Au bout du troisième jour du congrès, nous n’étions toujours pas parvenus à nous voir ; j’ai alors bien compris que son temps était limité. Cette année, me confirmait-il par message téléphonique, l’argent coule à flot. Quelques foreurs avec lesquels je me suis entretenu m’indiquaient qu’un certain intérêt commençait de nouveau à se manifester pour cette activité ; cependant, aucun d’eux n’était prêt à affirmer que l’on voyait enfin poindre la lumière tant attendue au bout du tunnel. L’un de mes contacts travaillant pour un équipementier spécialisé dans la production à la mine me confiait cependant que depuis l’automne, les commandes allaient bon train, et qu’ils fonctionnaient à plein régime en ce moment. Depuis quelques années, les porte-parole de l’industrie préconisent de faire preuve d’un optimisme prudent, aussi nous avons fini par nous abandonner à ce sentiment. En ce qui concerne la prudence, il faut certes rester sur ses gardes à bien des égards. À l’occasion du congrès, l’économiste Jon Butcher de Wood Mackenzie abordait dans son examen de la situation macroéconomique trois tendances, à savoir la lenteur de la croissance économique mondiale, le nombre relativement moins important de personnes en âge de travailler à l’échelle internationale ainsi que la dette considérable des ménages en Chine. Cela étant, si la croissance mesurée pourrait ne pas générer autant de valeurs minières extrêmement rentables et aux perspectives de profits alléchantes qui n’existent que dans les légendes, elle constitue probablement un environnement plus propice pour entreprendre des projets. Pour terminer, je tiens à féliciter Roy Slack de Cementation Canada qui est parvenu à capter l’imagination des membres du jury et des participants du concours Disrupt Mining avec sa présentation exposant l’idée de sa société concernant un système de levage à injection entraîné par pompe. Vous en trouverez la description dans une vidéo sur notre chaîne YouTube ; regardez-la, elle en vaut vraiment la peine.

Vers le début de mon mandat de président de l’ICM, j’ai rencontré Dick McIvor lors d’une réunion de division à Sudbury. Dick est membre à vie de l’ICM et spécialiste en levage. Il m’a chargé du « ralliement des mineurs ». Il souhaitait en effet que l’ICM motive davantage d’intervenants dans les tâches d’exploitation à participer aux réunions de division : des géologues, des ingénieurs des mines, des spécialistes des traitements, des gestionnaires et d’autres membres du personnel du secteur minier. Cette contribution stimulerait ainsi à son tour la participation de nos conseillers, sous-traitants et fournisseurs du secteur. Dick souhaitait également qu’un plus grand nombre de dirigeants supérieurs du secteur minier interviennent localement auprès de l’ICM, afin d’encourager la participation de la jeune génération de professionnels. À maintes reprises au cours de ma carrière, j’ai été récompensé de mon adhésion à notre association, qu’il s’agisse de réseautage ou de l’acquisition de connaissances techniques, organisationnelles ou de direction. Je suis fermement convaincu des avantages de devenir membre de l’ICM et souhaite encourager autant de personnes que possible à se joindre à nous. Tout comme l’ensemble du secteur minier, l’ICM a rencontré de nombreux défis au cours du ralentissement économique de ces six dernières années. Le nombre de nos adhérents a baissé ainsi que nos finances. Nous devons recouvrer une masse critique de membres, afin de continuer à fournir les services de haute qualité qu’offre l’ICM. Pour ce faire, nous disposons d’un plan d’action relatif à l’adhésion et notre conseil ainsi que le bureau national s’y concentrent en priorité. Attentif à ma tâche, je me suis rendu aux événements de l’ICM dans l’ensemble du pays et j’ai travaillé assidûment à enjoindre un grand nombre de personnes, allant d’anciens collègues de ma génération à des étudiants, à participer à l’ICM. J’ai encouragé la diversité afin de promouvoir une meilleure représentation des femmes, des Premières Nations, des minorités visibles et d’autres intervenants de l’ICM et de notre secteur. Si vous lisez ce mémo, vous êtes probablement déjà membre national de l’ICM et je prêche auprès de convertis. Je vous demande cependant de faire participer vos collègues non membres. Invitez-les aux réunions de division et aux événements sociaux. Faites-leur part des avantages de devenir membre national : les occasions de réseautage, les conventions, le perfectionnement technique et professionnel grâce à OneMine et EduMine, les communiqués numériques et imprimés, entre nombreux autres. Joignez-vous à moi dans cette mission de « ralliement des mineurs » à l’ICM!

Energie et productivite

La mine Éléonore, située dans la région subarctique du Québec, est l’une des dix mines qu’exploite Goldcorp dans les Amériques ; toutes ont des directeurs de l’énergie dédiés qui sont chargés de scrupuleusement examiner la consommation d’énergie sur le site.

La gestion de l’énergie devient de plus en plus importante pour les sociétés minières qui doivent faire face à la hausse des coûts de l’énergie et des émissions de gaz à effet de serre (GES). Selon des données de Ressources naturelles Canada (RNCan), les coûts de l’électricité et du carburant dans le secteur canadien de l’exploitation minière en roche dure ont augmenté de 20 % entre 2012 et 2014, passant de 15 % des coûts de production à 16,7 %. Toute stratégie efficace, quelle que soit la forme qu’elle revêt, exigera une approche organisée bénéficiant de l’appui de la haute direction, une capacité d’adaptation du site et la participation du personnel. La pression exercée par la hausse des coûts de l’énergie, conjuguée aux enjeux liés à l’environnement ainsi qu’à la

santé et la sécurité, pose un défi complexe à Goldcorp, qui exploite 10 mines en activité et 3 projets de développement dans les Amériques. « Nous constatons déjà l’augmentation des coûts de l’énergie et nous investissons aujourd’hui dans des mines dont l’exploitation commencera d’ici 10 ou 12 ans », déclarait John Mullally, directeur des relations gouvernementales et de l’énergie chez Goldcorp. « L’incidence de ces effets de coûts se fait déjà sentir aujourd’hui, et ceux-ci risquent d’être nettement plus élevés d’ici cinq ou sept ans. » Si l’on ajoute les conséquences du diesel sur la santé et les enjeux environnementaux liés aux GES, « tous ces coûts finissent par avoir des répercussions sur la productivité et la viabilité de l’entreprise ». March/April 2017 • Mars/Avril 2017 | 71

Le système d’aérage à la demande de la mine Éléonore inclut un suivi du personnel à l’aide de casques de protection équipés d’étiquettes d’identification par radiofréquence (RFID) pour s’assurer que l’on concentre l’aérage là où il est réellement nécessaire.

En 2012, Goldcorp a établi pour les cinq années à venir des objectifs globaux en matière de sources d’énergie renouvelables (puiser 5 % de son énergie dans les sources renouvelables), de réduction des GES (les diminuer de 20 %) et d’efficacité énergétique (l’accroître de 15 %). Par ailleurs, chaque site minier a établi ses propres objectifs. La mine Musselwhite, en Ontario, a mis l’accent sur le dénoyage, l’amélioration de l’aérage et le contrôle des pointes de consommation d’électricité. À la mine Peñasquito, au Mexique, la pulvérisation est devenue plus performante grâce à l’installation de cylindres de broyage à haute pression (HPGR, de l’anglais highpressure grinding roll) et à des techniques d’abattage à l’explosif qui ont amélioré la charge d’alimentation. « Ces recommandations sont faites par des experts en la matière, et dans ce cas précis, notre expert est le directeur de l’énergie [de chaque site] », poursuivait M. Mullally. « Avec la création du poste de directeur de l’énergie, la responsabilité de la consommation d’énergie revient à une seule personne, ce qui nous permet de mieux surveiller nos mesures de conservation de l’énergie et de mieux y adhérer. » 72 | CIM Magazine | Vol. 12, No. 2

La culture de la conservation Le rôle du directeur de l’énergie est de sensibiliser toutes les parties impliquées à l’importance de l’énergie dans toutes les activités de la société, petite ou grande. « Les ampoules halogènes consomment dix fois plus d’énergie que les DEL », rappelait M. Mullally. « Dans des installations aussi énergivores qu’une mine, les économies se chiffrent à des centaines de milliers de dollars par an. » Il est tout aussi important pour le directeur de l’énergie d’instaurer une culture de sensibilisation aux enjeux d’ordre énergétique parmi ses employés. D’après Andrew Cooper, spécialiste de l’énergie à la mine New Afton de New Gold, en

Colombie-Britannique (C.-B.), on sous-estime cet aspect de la gestion énergétique. « Nous traversons une période où nous ne percevons que le côté enivrant de la gestion de l’énergie », indiquait-il. « Nous nous laissons séduire par les énergies renouvelables, les nouvelles technologies et les données massives. » Pourtant, certaines des économies les plus importantes découlent de bonnes habitudes de conservation de l’énergie, par exemple des gestes aussi simples que de faire couler l’eau froide plutôt que l’eau chaude. « Tout a son importance, je ne dis pas le contraire, mais je pense que l’on a perdu de vue l’essentiel. On remplace notre source d’énergie actuelle par une source d’énergie renouvelable, que l’on continue de gaspiller. » À la mine New Afton, la sensibilisation aux enjeux d’ordre énergétique a été un élément central de la mise en œuvre de la certification ISO 50001, dont les démarches ont commencé en 2013 et ont mené à l’obtention en 2014 de cette certification relative à la norme internationale pour la gestion de l’énergie. Depuis, comme indiquait M. Cooper, le temps consacré à la sensibilisation n’a presque pas diminué. « Tous les ans, nous devons dispenser différentes formations à différents groupes, puis des mises à niveau propres aux activités de chacun, si bien que cela nous occupe presque autant qu’avant. Nous devons maintenir le cap et proposer des solutions qui préserveront l’intérêt et l’enthousiasme. » En 2016, un membre de l’équipe de gestion énergétique de la mine New Afton a proposé une campagne de sensibilisation très intéressante. La société FLIR Systems produit un dispositif d’imagerie thermique qui se branche sur un téléphone intelligent. « Nous en avons acheté une grande quantité et organisé une campagne de sensibilisation afin d’encourager les employés à les emprunter afin de mesurer les pertes d’énergie dans leur maison, au niveau des portes, des fenêtres, du chauffe-eau, des systèmes de chauffage, etc. », expliquait M. Cooper. Les employés ont pu échanger leurs photos à l’aide de l’application SharePoint. « Cette campagne est très stimulante ; elle contribue, selon nous, à sensibiliser les gens à la consommation énergétique au sein même de leur foyer, ce qui automatiquement a des retombées positives au travail. » Quand les employés s’impliquent, ils commencent à trouver de bonnes idées. Un mécanicien de la mine New Afton a proposé d’ajuster les réglages du compresseur, ce qui a donné lieu à une économie d’énergie annuelle de 0,9 gigawatt (GW). « C’est un exemple d’initiative totalement gratuite prise par un employé », se réjouissait M. Cooper. La gestion de l’air comprimé, lequel peut engendrer de grands gaspillages d’énergie, est une économie évidente, simple et peu coûteuse. À la mine Red Lake, la principale difficulté qu’a rencontrée Goldcorp lors de sa campagne de réduction du gaspillage généré par les composants usés des compresseurs d’air a été de sensibiliser tous les employés à ce problème et de les convaincre de faire preuve d’initiative. « Même s’il s’agit d’un effort peu coûteux en termes de capital, la coordination n’en demeure pas moins exigeante », reconnaissait M. Mullally. « C’est d’ailleurs le directeur de l’énergie qui est chargé d’assurer le lancement de l’initiative ainsi que les communications et le suivi des résultats, sans oublier, le

cas échéant, les motivations et les récompenses inhérentes au travail accompli. » À l’autre extrémité du spectre des coûts, l’aérage à la demande requiert d’importants investissements en termes de systèmes et de logiciels, mais permet de réaliser de grandes économies en ne démarrant les ventilateurs qu’en fonction des besoins. « Nous injectons 25 millions $ par an dans l’aérage de nos mines souterraines en Ontario », indiquait M. Mullally. « C’est une dépense importante. Dans nos mines ontariennes, l’aérage représente 50 % de la consommation d’électricité. Par conséquent, toute initiative qui réduit la consommation attribuable à l’aérage est accueillie à bras ouvert. » À la mine Éléonore de Goldcorp, l’aérage à la demande a été intégré à l’étape de la construction de la mine, ce qui sera également le cas à la mine Borden Lake. Les projets nécessitant d’importants capitaux, aussi efficaces soient-ils, ne sont pas à la portée de toutes les mines. Mary Stewart, directrice générale du cabinet-conseil australien Energetics, reconnaît que l’accès au capital est un grand problème pour les petites sociétés. « Certaines d’entre elles n’ont pas les moyens de s’offrir de grandes améliorations », déclarait-elle, ajoutant que si les petites sociétés sont souvent les mieux placées pour innover, ce sont aussi celles qui, ironie du sort, ont le moins de capital à disposition pour le faire.

Les énergies renouvelables Les projets d’énergies renouvelables ont gagné du terrain à l’échelle mondiale. Ils offrent une protection contre la hausse future des coûts liés à l’énergie et assurent un approvisionnement possible en énergie dans des lieux non raccordés au réseau électrique. Dans le Grand Nord canadien, la mine de diamants Diavik a ouvert la voie en construisant un parc éolien en 2012, réduisant ainsi la demande de diesel. En 2016, Glencore a également installé une éolienne à sa mine de nickel Raglan. La même année, Sandfire Resources a installé une centrale photovoltaïque à sa mine reculée de cuivre et d’or DeGrussa, en Australie-Occidentale. Ce projet de 40 millions $ produira environ 20 % de l’énergie annuelle nécessaire à l’exploitation de la mine, en complément de la production de la centrale au diesel. « Au vu du prix à la baisse des batteries, ces systèmes hybrides deviennent de plus en plus avantageux, avec ou sans accès au réseau », soulignait Mme Stewart. « Une fois remboursés les coûts engagés dans les énergies renouvelables, on se retrouve au final avec une source d’énergie gratuite », ajoutait-elle. « Cela permet de prolonger la durée de vie de la mine ; en effet, lorsque la teneur en minerai diminue, l’énergie est encore si bon marché qu’il est rentable d’extraire le minerai et de le traiter. »

Les enjeux liés aux pointes de consommation Même pour une mine raccordée au réseau, une source d’énergie autonome et rentable peut constituer la réponse au March/April 2017 • Mars/Avril 2017 | 73

nouvel enjeu que représente la tarification applicable à l’énergie consommée pendant une période de pointe. Selon Mme Stewart, les marchés de l’électricité ont délaissé facturation établie en fonction de l’utilisation du réseau au la profit de la facturation fondée sur les capacités du réseau. « La tarification fondée sur la capacité est appliquée au marché de la côte est de l’Australie », précisait-elle. « Elle représente la majeure partie des réseaux électriques du pays et comprend tous les producteurs d’électricité, exploitants de réseaux et détaillants. Le Canada, les États-Unis et l’Europe ont aussi adopté ce type de tarification, à des degrés divers et en fonction de leur marché. » Selon ce mode de facturation, la facture d’électricité de la mine est établie en fonction de la capacité requise pour répondre à ses pointes de consommation. Les coûts des pointes de consommation ne se contrôlent pas comme ceux inhérents à la consommation générale. Par exemple, la consommation de pointe survient souvent au moment du démarrage d’équipements lourds. Pour la réduire, la mine pourrait démarrer ces machines lorsque sa consommation d’énergie est plus faible dans une autre partie de l’exploitation. Elle pourrait aussi installer des variateurs de vitesse ou encore des mécanismes de démarrage progressif. « Il existe des méthodes plus sophistiquées ; on peut, par exemple, analyser le flux d’énergie et s’assurer que la charge du site est gérée de manière à éviter les pointes », expliquait Mme Stewart. Le responsable du site n’est pas nécessairement au courant de cette tarification, les contrats n’étant habituellement pas négociés sur place. Les détails et les complexités des contrats d’électricité sont au cœur des échanges de Mme Stewart avec les grandes sociétés cotées à l’ASX (la bourse des valeurs mobilières australienne), qui constituent la base de la clientèle d’Energetics pour l’industrie minière. Les objectifs de conservation de l’énergie sont souvent décrits en fonction de l’efficacité énergétique des processus ou de l’équipement, qui se calcule en « kilowattheures (kWh) par tonne de minerai traité ». Mme Stewart propose autre chose à ses clients, à savoir la productivité énergétique. « L’important, c’est le rapport entre chaque dollar d’énergie investi pour chaque dollar de valeur créée, et cela change la perspective. » Aux États-Unis, au Canada, en Australie et plus récemment en Amérique du Sud, on analyse les économies d’énergie sous cet angle. « On parlera moins de l’efficacité énergétique classique, car l’accent devra être mis sur la manière de dépenser l’argent puisque les coûts ne seront plus les mêmes », poursuivait-elle. « Il faut déterminer ce qu’un dollar d’énergie permet d’acheter, et non le rendement qu’il dégage. » Les structures tarifaires complexes peuvent accaparer une bonne partie du temps du spécialiste de l’énergie. Selon le programme de rajustement global mis en œuvre par la province de l’Ontario, les mines de Goldcorp paient un supplément pour leur consommation dans les cinq jours de l’année au cours desquels la consommation à l’échelle de la province a atteint des pointes. Comme il est impossible de prévoir que la consommation élevée d’une journée correspondra à l’une des cinq pointes retenues, la mine qui essaie de contrôler ces pointes de consommation s’efforcera de réduire sa production 74 | CIM Magazine | Vol. 12, No. 2

les jours qui, selon elle, pourraient devenir des journées de pointe. La structure tarifaire de l’Ontario peut s’avérer particulièrement complexe. « En Colombie-Britannique, c’est relativement simple », expliquait M. Cooper. « Depuis trois ou quatre ans, nous connaissons d’avance nos pointes et pouvons les prévoir dans le budget. C’est beaucoup plus prévisible ici qu’en Ontario. En outre, nous n’avons pas ce problème de rajustement global. » Comme le précisait M. Cooper, le fournisseur d’électricité de la mine New Afton, BC Hydro, calcule la demande maximale, mais sans qu’elle ne soit affectée négativement par les démarrages de moteurs, et la réduction de la consommation ne vise pas spécialement la consommation de pointe. Les objectifs de conservation d’énergie de la mine New Afton sont également simples. Au lieu de mesurer les économies d’énergie en fonction de l’efficacité ou de la productivité, la mine a choisi une méthode qui lui paraissait simple et réalisable. Elle prend la consommation énergétique totale de l’année précédente, calcule un pourcentage de cette consommation et fait de la valeur obtenue son objectif pour l’année suivante. Par exemple, en 2016, New Afton a pris sa consommation de 2015 en kWh ou gigajoules, a calculé 1 % de la valeur totale et a planifié la mise en œuvre de projets qui réduiraient sa consommation de 2017 de la valeur obtenue, soit 2,74 gigawattheures (GWh). Même si la consommation énergétique totale de la mine augmente durant l’année, en raison par exemple d’une hausse de la capacité, elle aura tout de même réussi à réaliser des économies d’énergie dans les projets mis en œuvre. En 2016, New Afton ciblait une réduction de 2,54 GWh et, en fin de compte, elle est parvenue à des économies de 4,5 GWh. « L’objectif est facile à établir et à quantifier, et nous pouvons l’atteindre. C’est une méthode très simple et, qui plus est, qui fonctionne », concluait M. Cooper. Dans une mine qui se développe et change constamment, il n’est pas toujours aussi simple d’établir des objectifs pertinents et réalistes. « Les mines deviennent plus profondes, les caractéristiques de la roche évoluent et le corps minéralisé devient plus ou moins complexe, si bien qu’il est difficile de planifier une amélioration relative [aux coûts de base] », expliquait AUTRES ARTICLES Mme Stewart. « D’où l’utilité d’une valeur simple qui unifie tout le CIM Magazine monde. » Alimentation en Certaines sociétés minières air à la demande songent à établir leurs objectifs de Par Krystyna Lagowski réduction des GES en fonction des cibles internationales qui plafonDes gains incontestables nent la hausse des températures à d’eﬃcacité : l’échelle mondiale à deux degrés New Afton est la Celsius (2°C), « mais cela exige première mine d’importantes réductions des émisd’Amérique du Nord à obtenir la certiﬁcation sions », déclarait Mme Stewart.

Structural equation modelling of leaching of oxidized copper-cobalt ore in a hydrochloric acid solution M. B. Kime, University of Johannesburg, Johannesburg, South Africa

A set of experimental batch leaching tests studied the effect of pH, time, temperature, and stirring speed on the relative Cu, Co, Ni, and Fe leaching yields of an oxidized copper-cobalt ore sample in an aqueous hydrochloric acid solution. The results were statistically analyzed and modelled using the structural equation modelling method. Models showed that Cu, Co, and Ni leaching yields were strong functions of the leaching time and leaching temperature, whereas the Fe leaching yield depended on the leaching temperature, stirring speed, and pH. Under optimum leaching conditions yields were 99.8% Cu, 82.4% Co, 91.3% Ni, and 30.6% Fe.

Agnico Eagle LaRonde plant: Metallurgical challenges present and future C. Bolduc and J. Cayouette, Agnico Eagle Mines Limited, Rouyn-Noranda, Quebec, Canada; and P. Blatter, GreenStone Gold Mines, Toronto, Ontario, Canada

Commissioned in 1988, the LaRonde mill has been treating ore since 2000. The mill has been expanded to accommodate 7,500 t/day, but ramped down to 6,000 t/day since the deep extension began. The process recovers gold, silver, and base metals. In 2008, the Goldex plant began trucking goldpyrite concentrate to a treatment plant feeding pulp to the LaRonde mill, increasing gold output by 40,000 oz. In 2009, the high-grade Lapa ore processing facilities were annexed to the LaRonde plant, increasing gold output by 120,000 oz. This paper outlines the metallurgical considerations related to the treatment of different ore types.

Using the discrete-element method to investigate ball milling power draw, load behaviour, and impact energy profile M. B. Kime, University of Johannesburg, Johannesburg, South Africa

Discrete-element method (DEM) modelling is a powerful tool for studying particulate systems within the mineral processing industry. DEM simulations were conducted to investigate the power draw, load behaviour, and impact energy profile of an experimental ball mill under different milling conditions. The variables considered were mill rotational speed (percent critical speed), ball size, and lifter face angle. The simulation results indicated that the grinding efficiency would be enhanced by using 80% critical speed, 30 mm ball diameter, and 45° lifter face angle. These findings can be useful in guiding actual ball milling tests involving an ore sample.

Flowsheet development, commissioning, and start-up of the Voisey’s Bay mill P. F. Wells, CVRD-Inco Technical Services Limited, Sheridan Park, Mississauga, Ontario and P. F.

in 2001, the target grade was raised to 20% Ni. Initially triethylene tetramine and sulfite pyrrhotite depressants were used in a lime circuit, but by recycling process water and the contained thiosalts, the required nickel grade was made without depressants. Construction of the mill was fast-tracked, with start-up in September 2005. Ramp-up was faster than other recent nickel installations, with tonnage being limited by concentrate dewatering due to higher-than-expected ore grades.

Operating experience and developments of G-REX and AuRIX®100 resin exchange technology P. Richards, A. Lewis-Gray, and N. Katsikaros, Gekko Systems Pty Ltd., Ballarat, Australia; and M. Davies, Castlemaine Goldfields, Mount Clear, Australia

To optimize gold recovery in complex leach-to-electrowinning processes, Gekko Systems developed the Gekko resin exchange column (G-REX) as an intermediate step, using a highly gold-selective resin to isolate contaminant metals. The AuRIX®100 resin produced by Purolite is licensed exclusively to Gekko, with the G-REX column designed specifically for this resin. Operational experience has been gained at the Castlemaine Goldfields Ballarat gold mine. In near-continuous operation since 2008, the Ballarat plant treats unclarified concentrate leach solution. The extension of this technology to higher throughputs and more complex chemistry is discussed.

Copper prestrip to copper cyanide S. N. Dixon, SND Consulting, Tucson, Arizona, USA

Maximizing the value of each tonne of processed ore is the goal for all operations. Cyanidation processing of gold-copper ores has been challenging since its first use in 1889. The current practice treats a bleed or the total flow of mill solution to recover copper as copper sulfide (by sulfidization, acidification, recycling, and thickening), or to recover the cyanide (by acidification-volatilization-neutralization). The process presented uses the adsorption of copper cyanide by carbon and the selective elution of copper from carbon to concentrate copper into a smaller stream. Copper contained in the smaller stream is precipitated as copper cyanide.

Experimental and numerical investigations of fluid flow in a hydrocyclone without an air core E. Kucukal and J. R. Kadambi, Case Western Reserve University, Cleveland, Ohio, USA; J. Furlan and R. Visintainer, GIW Industries, Grovetown, Georgia, USA

Hydrocyclones are used in various industrial applications, including mineral processing and tailings management, to separate or classify solid particles and/or liquid droplets from multiphase feed. The fluid flow in a hydrocyclone (used in mineral processing) was investigated numerically and experimentally using particle-image velocimetry (PIV) and refractive index matching techniques. Two turbulence models were used in the calculations: the k– model and the Reynolds stress model. Particle image velocimetry measurements were taken at various spatial locations along the cyclone. Computational results were validated globally using pressure and flow-rate readings at the boundaries, and locally by comparing the PIV velocity-vector maps and profiles.
