DEVELOPING MULTIPLE REVENUE STREAMS FROM ITS WHITE MOUNTAIN ANORTHOSITE MINE IN GREENLAND

udson Resources celebrated the safe arrival of the first bulk shipment of anorthosite (calcium feldspar) from its

White Mountain (Qaqortorsuaq) Greenland mine in August this year. It’s set to be the first of many shipments taking advantage of a unique orebody 12

with a +100-year mine life. “The journey to the commencement of production of the anorthosite at White Mountain in February 2019 has taken seven years,” explains President and Director Jim Cambon. With a 50-year permit in place, we embarked on our 12-month plan to develop the mine site in 2018. The creation of the mine and associated infrastructure was a CA$45mn construction project utilising a modular approach, with 1200 tonnes of steel brought in to the remote Greenland location by barge. “That barge is now our dock at the deep-water port,” adds Vice President of Operations, Jerry Janik, who recalls the logistical challenges of commissioning the process plant during the Arctic winter. “It was -40°C when we first commissioned the site – 12 months earlier the plant was just a slab of concrete.

“ IT WAS -40°C WHEN WE FIRST COMMISSIONED THE SITE – LAST YEAR THE PLANT WAS JUST A SLAB OF CONCRETE. THE EXECUTION OF THE CONSTRUCTION PHASE WAS A GREAT SUCCESS AND MET ALL OF OUR EXPECTATIONS FROM A SAFETY, COST AND SCHEDULING PERSPECTIVE” — Jerry Janik, Vice President, Operations, Hudson Resources

construction phase was a great success and met all of our expectations from a safety, cost and scheduling perspective. It’s a great reflection of the excellent team we assembled, boosted by the skilled workforce here in Greenland and the engineering led by CWA Engineers in Vancouver.” Greenland is a self-governing administrative jurisdiction of Denmark with control of its mineral rights. With no land claim issues, Hudson deals directly with the Greenlandic people and has very strong support from the local communities. Greenland is a mining friendly jurisdiction with a competitive fiscal regime that provides a sound financial basis for the future of White Mountain. The Greenland School of Minerals and Petroleum Råstofskolen is also located near White Mountain; it has toured the facility. Anorthosite, which is 30% aluminum, offers Hudson the opportunity to develop products with multiple revenue streams. Hudson’s GreenSpar is derived from the igneous mineral plagioclase, which yields the hardest feldspar with the highest refractive index, and offers a distinct advantage as a premium mineral extender for

Enduring solutions to last a mine’s life At Weir, our engineers have been solving the mining industry’s biggest operational challenges since 1871. Today we have 15,000 people in over 50 countries serving the mining sector alongside the infrastructure and oil & gas markets. We can improve the processes at your mine site with everything from slurry transportation, mine dewatering systems and classification & separation to wear lining & corrosion protection, tailings management and crushing & grinding.

Crushing & Grinding Our high capacity crushing and grinding equipment was conceived to process a wide range of applications from primary, secondary, and tertiary hard rock crushing. Weir’s Enduron equipment is tough, reliable and designed to maximise performance. Built for extra-long service life, our entire range of crushing and grinding solutions is backed by the Weir Minerals Service network operating in over 70 countries across the globe.

Conquering the mountain When Hudson Resources needed a tailored solution to meet its crushing and grinding needs at the White Mountain anorthosite mine in Greenland, Weir had the answer. Anorthosite’s dust can interfere with magnetic separation so Hudson commissioned Weir to deliver a crushing and fine grinding system using high pressure grinding rolls (HPGR). “The Enduron HPGR requires little to no water for size reduction and has 30% less power consumption versus standard crushing circuits,” explains Weir’s North American HPGR Manager Tim Lundquist. “Since Hudson is creating a dry product in a remote location both of these factors were vitally important to the success of the operation.” Hudson’s Vice President Jerry Janik was impressed: “What Weir provided was unique. It enabled us to generate sand and less dust during the second stage of crushing.” Used in mining applications for the last 30 years, HPGR reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding their compressive strength with equal pressure being applied to particles of all sizes.

WHY HPGR? Decrease your energy consumption by up to 30% Reduce recirculation and wear within your crushing circuits Enhance your downstream mineral liberation Reduce your maintenance requirements Substantially reduce your water consumption

With their excellent throughput capacity, low maintenance requirements and energy efficiency, high pressure grinding rolls are fast becoming a go-to for greenfield projects looking to maintain their margins despite commodity price pressures and declining ore grades. On average, 53% of a mine site’s energy consumption is attributed to crushing and grinding ores accounting for almost 10% of a site’s production costs. Where HPGR technology has replaced traditional methods of crushing and grinding customers have seen energy savings, and substantially improved mineral liberation. “Weir’s goal

is always to provide a solution and not just a product,” pledges Lundquist. “When the opportunity arises to work with a company like Hudson we take a look at the entire process as part of offering equipment. Additionally, we undergo testing to verify our solution will meet the client requirements and do not stop working until our promises have been met.” enduron@mail.weir www.global.weir

Weir was also commissioned to supply the in-plant crushers. “The ones we’re using are high pressure grinding rolls,” reveals Janik. “They’re somewhat different than what you’d normally expect. The fine dust can interfere with the magnetic separation. What Weir provides is unique, enabling us to generate sand and less dust during the second stage of crushing.” Elsewhere, Lillegaarden was employed to head up the electrical work at the plant. “I’ve been in this business for 30 years and can say it’s the cleanest, most high-quality layout I’ve ever seen,”

Hudson’s lunar research White Mountain anorthosite is being tested by space agencies as a potential lunar simulant to be used for testing lunar equipment such as rovers, and as a potential building material using Hudson’s CO2 free Anocrete concrete. Future lunar missions are planned to travel to the Lunar Highlands and the Lunar Poles where the main geological environment is anorthosite (very similar to Hudson’s anorthosite in Greenland). Lunar anorthosite was collected by the Apollo missions in the early 1970s. Hudson is collaborating with lunar scientists at the University of Tokyo, who are at the forefront of space research. The University of Tokyo developed petrological sections and

conducted tests which confirmed that Hudson’s anorthosite is very similar to the Lunar Highland material in texture, grain size and constituent minerals. Hudson and the University of Tokyo are also in discussions with regard to collaborating on research and development on concrete applications using Hudson’s CO2 free Anocrete concrete. Hudson has provided material to NASA’s Johnson Space Center for evaluation to use in its testing facilities for rover simulations. The company has also held preliminary discussions with the European Space Agency regarding utilising Hudson’s anorthosite for lunar research.

just a matter of time. We keep going through these cycles where exploration ramps up, but then the Chinese lower rare earth prices. Eventually they will run out of material, or will want to use it internally, and that’s going to be a huge problem for the rest of the world. Realising sustainable, green, environmentally friendly rare earth projects is an important challenge to meet and one where we’ll look at finding the right partners to tackle.” Next year, Cambon expects White Mountain to be producing material for paint and E-glass customers, and hopefully rockwool too. “We are in detailed discussions with a fair number of potential off-take partners,” he says. “I think by 2021 we’ll be sold out. We won’t have the ability to take on new customers until we can expand; it’s a nice problem to have. By year three we’ll be looking at doubling the size of the operation. I think that’s just the reality of the demands we’re going to see for anorthosite.”

Sales are expected to rise from two million units in 2018 to 21 million units by 2030. Several long-term trends are driving growth in copper demand and are expected to amplify in the coming decades. Along with the wider uptake of EVs, the boom in consumer electronics, the increased use of renewable energy sources and energy efficiency — coupled with the need for battery storage solutions — all require significant amounts of copper to function, with analysts forecasting a ten-fold rise in demand by 2050: A reason why Friedland was keen to talk up the potential of his company, Ivanhoe Mines’ projects in the Democratic DECEMBER 2019

The rise of copper will herald “the revenge of the miners” declared Friedland, whose no-nonsense appraisal of the industry’s likely inability to meet demand for the strategic metal had the packed auditorium hanging on his every word. “Human beings wanting everything, all of the time and moving to cities will drive that growth in demand,” he said, alluding to the opportunity for the industry to make a positive contribution to the fight against air pollution and the w w w.mi ni nggl o b a l. com

HOW LARGO RESOURCES IS MINING BRAZIL’S VANADIUM EFFICIENTLY AND SUSTAINABLY When a winning strategy is executed by talented, passionate professionals in favourable conditions, the results can be spectacular. Last year, Largo Resources experienced just that when vanadium production at its Maracás Menchen mine in Brazil went up 2% year on year, reaching 2,595 tonnes. This helped drive a record full year production of 9,830 tonnes, representing 48

an increase of 6% over 2017, and the strongest full year of production since operations began in 2014. The company subsequently reported revenues of CA$521.4mn – a 211% increase year on year. A strategic mineral company utilising the latest technologies, Largo is focused on the production of high purity vanadium flake and vanadium powder. A transitional metal, vanadium steel alloys are used in the production of gears, axles and crankshafts. The metal is also in demand for energy storage solutions, a fast-growing component of the infrastructure needed to accommodate the global shift to renewable energy. DECEMBER 2019

GLOBAL MINING GUIDELINES GROUP: 58

LEADING THE INNOVATION CONVERSATION WRITTEN BY

DAN BRIGHT MORE

The Global Mining Guidelines Groupâ&#x20AC;&#x2122;s (GMG) Chair, Michelle Ash, discusses the challenges facing the industry and how the GMG is supporting safety and sustainability while promoting education around digitisation

DECEMBER 2019

w w w.mi ni nggl o b a l. com

TECHNOLOGY

he Global Mining Guidelines Group (GMG) is a network of representatives from mining companies, OEMs, OTMs, research

organisations, consultants and regulators around the world who collaborate to tackle challenges facing the industry. Founded in 2013, its original goal was to urge mining companies to come together to consider comminution technologies, reduce energy consumption and improve their sustainability efforts. Joining together with SMART, they started the conversation around automation, interoperability and safety; becoming a hub for collaboration and innovation focused on technological enablement. 60

“How do we get the mining ecosystem to work collaboratively? What does interoperability in test automation mean?” GMG Chair Michelle Ash remembers the big questions facing the industry at that time: “I think the challenge for the organisation at its inception was most probably a little too early, because automation technology was still the domain of the major mining companies, while others were still playing catch up.” She recalls that members’ needs at that time were focused on the emergence of electric vehicles and the battery metals required. “It was a topic that got mining companies to start collaborating on setting guidelines for our supplier community, to try to get some of this technology into our mining sites and make an impact on sustainability performance, reduce diesel usage and improve health outcomes for our industry’s employees.” DECEMBER 2019

GUIDING THE INDUSTRY Gathering a head of steam, the organisation has since released several guidelines covering battery electric vehicles (EVs), communication systems and automation. “We’re just through launching guidelines on functional safety and interoperability,” Ash says. “We’ve matured a lot as an organisation, to the point where we can address our main aim and get the mining ecosystem to embrace collaboration.” The GMG looks at how technologies such as IIoT, predictive analytics w w w.mi ni nggl o b a l. com

and AI can transform the industry, how they might be implemented and what the business case looks like. “We aim to fast track their implementation and therefore speed up the rate of transformation across the sector,” confirms Ash. “We’re expanding our reach and are able to talk about these topics across North and South America, through Europe and Australasia, because we’ve got members all over the globe with a diverse range of companies active in our ecosystem.” Prominent leadership

Inmarsat Inmarsat is a high-profile addition to the GMG family, recently becoming its 25th leadership member. A world leader in satellite communications, it has a lot to offer the mining industry. In collaboration with Knight Piésold UK it is delivering remote tailings dam monitoring with real-time analysis. Inmarsat’s satellite-enabled IoT (Internet of Things) solution collects data from a range of industry standard sensors via edge connectivity such as LoRaWAN (Long Range Wide Area Network), before it is transferred across Inmarsat’s L-band satellite network to a single cloud dashboard. This enables mining

companies and national regulators to gain a comprehensive view of the status of their dams with granular metrics such as pond elevation, piezometric pressures, inclinometer readings and weather conditions displayed in one place, no matter where the mine is located. The solution also features sensor-agnostic capabilities, so it can work with both existing sensors and new devices. “They offer support for even the smallest, and most remote, mining companies to consider the benefits of tailings data management and enhance safety across the industry,” confirms GMG’s Chair Michelle Ash.

REACTING TO TRENDS The GMG is alert to the changing landscape of issues affecting the industry. Prominent among these is concern regarding cybersecurity. “It’s a topic that’s really only started becoming the remit of mining companies over the last DECEMBER 2019

couple of years,” notes Ash. “The leading mining companies have audit risk committees briefing their organisations on their in-house capability, but I’m really proud that over the last 18 months we’ve established a cybersecurity working group at GMG to offer those learnings to our whole mining community.” Tailings management is an issue that has dominated headlines across the sector this year following the tragic dam collapse at Brumadinho in Brazil. “Tailings dam design, management and ultimate eradication is something we at the GMG take very seriously,” says Ash. “We’re taking a collaborative approach to finding solutions and have provided detailed information of the publicly available projects for our members and the wider mining community through our website. From there, we can find the space for that collaborative work to flourish. We’re currently working at a strategic level with the ICMM’s independent review of tailings dam storage facilities.” The GMG also monitors health trends affecting the industry with particular attention being paid to the eradication of diesel equipment from underground w w w.mi ni nggl o b a l. com

ndigenous Women in Mining and Resources Australia (IWIMRA) launched in 2018, shaped by the experiences of its founder,

Florence Drummond. Conceived to offer a platform to showcase the stories of Aboriginal and Torres Strait Islander women in the sector, its aim is to support inclusion and diversity while signposting the pathways

that can guide others towards a career in the resources industry. “The genesis for IWIMRA was my own 72

experience working in the industry as a machine operator,” explains Drummond, who was previously employed at Rio Tinto’s Weipa bauxite operation in Queensland and now works as the Project Supervisor for Indigenous Engagement Strategy at BHP. “I worked in a remote location and struggled to really find opportunities to grow and progress within my career. When you’re physically isolated, you tend to feel you’re not part of the innovations that are happening in the industry. So, it was important to reach out and see if there was any support, specifically for Indigenous people – but there wasn’t any. It’s what led me to start the conversation on Facebook, to make social connections and identify if anyone else was feeling the same frustrations.” DECEMBER 2019

Acknowledging that there are many groups for women in mining, she instead highlights the lack of educational opportunities for Indigenous people as a further barrier to getting their voices heard. “How can we bring it back to basics with an approach that’s both comprehensible and accessible, while something that we, as Indigenous women, could feel safe participating in?” Finding the answer to that question, led Drummond to a simple discovery. w w w.mi ni nggl o b a l. com

Reconciliation Australia

“Reconciliation Australia acknowledges and pays respect to the past, present and future Traditional Custodians and Elders of this nation and the continuation of cultural, spiritual and educational practices of Aboriginal and Torres Strait Islander peoples.” Reconciliation Australia’s pledge is underpinned by a Reconciliation Action Plan (RAP) programme, which provides a framework for organisations to support the national reconciliation movement. Schools and early learning services can develop a RAP through Narragunnawali. Workplaces can be supported to develop one of four types of RAP: Reflect, Innovate, Stretch or Elevate.

DECEMBER 2019

A RAP is a strategic document that supports an organisation’s business plan. It includes practical actions that will drive an organisation’s contribution to reconciliation both internally and in the communities in which it operates. The RAP programme contributes to advancing the five dimensions of reconciliation by supporting organisations to develop respectful relationships and create meaningful opportunities with Aboriginal and Torres Strait Islander peoples. Each of the four RAP types (Reflect, Innovate, Stretch, Elevate) set out the minimum elements required from your organisation to build strong relationships, respect and opportunities within your organisation and community.

Drummond notes that, though mining companies are starting to do great things with their inclusion and diversity initiatives in the workplace, they need support from organisations like IWIMRA to contribute more effectively to the greater good. “Creating tools and problem solving together can be much more positive,” she asserts. “We need to build the capacity for Indigenous communities far beyond the workplace.” IWIMRA’s conversation around professional development for the Indigenous workforce across Australia’s

RISING COSTS

With the adoption of new technologies and issues around regulation, the complexity of mining increases and so do its associated costs. A focus on productivity can help manage the impact of rising costs. Companies need to realise the benefits automation and the growing maturity in the use of data can bring; driving a reduction in production costs per tonne. EY recommends: a focus on sustainable cost reduction programmes; innovation through long-term partnerships; divesting non-core assets; reviewing supplier/service contracts and capital tied up in stockpiles; outsourcing; back office 82

automation and strategic joint ventures to realise economies of scale.

DECEMBER 2019

INNOVATION

Being prepared to innovate and rethink how operations are run can lead to substantial productivity gains. Innovation can be the bridge to crossing over some of the major hurdles in the mining sector today. Faced with declining ore grades, the increased need to mine in remote locations, the cost of energy and infrastructure, rising operational complexity and the need to improve water management, radical approaches may be required and can succeed. Rio Tinto is leading the way with a â&#x20AC;&#x2DC;Mine of the Futureâ&#x20AC;&#x2122; programme embracing autonomous haulage systems and automated drilling systems linked to a centralised operations centre in Perth, connecting mines, ports and rail systems. w w w.mi ni nggl o b a l. com

REPLACEMENT OF PRODUCTION

â&#x20AC;&#x153;Lower exploration budgets, fewer major discoveries and declining grades in existing deposits are particularly concerning when you consider that the outlook is for growing mineral demand as a result of the global growth and the demands of new world infrastructure,â&#x20AC;? explains Paul Mitchell, EY Global Mining & Metals Advisory Leader. He notes that, despite some recovery, those budgets are still half what they were in 2012. To avoid the predicted supply crunch, EY advises strategies to increase access to capital, the acquisition of existing projects or mines and the leveraging of innovative technologies to uncover new resources while extracting further value from current ones.

DECEMBER 2019

CYBER

While data can hold the key to increasing productivity and reducing costs, as a business goes digital its â&#x20AC;&#x153;threat surfaceâ&#x20AC;? increases exponentially due to the expansion of the IT footprint through such areas as IoT sensors, data analytics and AI. This ramping threat has seen organisations spend more on cybersecurity, improving their defences to embed security-by-design. EY recommends that every cybersecurity transformation should promote three key principles across culture, governance and capabilities: excellence in security fundamentals, a strong governance program allied with a culture of accountability and continuous improvement. w w w.mi ni nggl o b a l. com

MAXIMISING PORTFOLIO RETURN

â&#x20AC;&#x153;Miners need to think more broadly about how to maximise their returns and adopt new approaches that may be radically different from those of the past. Mining companies will also need to re-evaluate their appetite for risk to ensure they are not missing out on new opportunities by taking a complacent or conservative approach to allocating capital,â&#x20AC;? warns Mitchell. To improve their options, EY suggests looking at opportunities to transform funding, rethinking a portfolio and exploring joint ventures.

DECEMBER 2019

HIGH IMPACT RISKS

New to this year’s list, EY asks: “Does the traditional risk matrix work for a mining company?” Mitchell concedes most mining companies have a clear understanding of their critical risks and are able to mitigate the visible, high frequency risks across their business. However, he warns that critical risks are often static on a company’s risk register in the same “format” for years. “Companies need to assess portfolios in terms of what would happen if something radical happens. For example, what if energy becomes free, then what happens to copper? There is a massive technological breakthrough in the composition of plastic or other advanced materials - how does that affect demand for metals?”

REDUCING CARBON FOOTPRINT

A global transition towards a low-carbon economy is making significant progress, driven by climate change fears and a strong focus on sustainability across industry sectors. Subsequently, the pressure is on the mining industry to reduce the impact of its carbon emissions and energy use. Mining majors are responding to the need to act with minimisation strategies including renewable energy, the electrification of mines and a focus on Scope 3 emissions. The transition to clean energies represents a huge opportunity for the industry to provide the minerals - lithium, cobalt, copper, aluminium and nickel - that will enable the storage of renewable energy harnessed through the use of solar and wind technologies.

DECEMBER 2019

DIGITAL

EY has previously highlighted that digital initiatives, such as the use of predictive analytics to reduce maintenance costs and improve equipment availability, have focused on solving bottlenecks and have not always been truly transformative. The challenge remains to better manage data to extract value and insights from it to drive operational excellence and real change. Mitchell urges the need to get the foundations right enabling people and data capabilities with connected data throughout an operation. The mantra â&#x20AC;&#x153;automate the science, enable the artâ&#x20AC;? can aid the extraction of value to make better decisions.

FUTURE OF WORKFORCE

Talent management practice often mirrors the commodity price cycle: miners hire rapidly in upswing and shed excess resources during the downturn. “Companies are grappling with understanding what the workforce might look like in the future, and where they can attain these skills - build or buy?” asks Mitchell. “Given the competitive 90

market for digital and data-related skills, they might be hard to get into the mining sector, given the tarnished brand we have versus other sectors.” EY stress the importance of finding ways to retain senior employees and minimise the effects of attrition while looking at ways to build, recruit or borrow the capabilities needed for transformation to flourish across an organisation. Big questions remain: how will you equip future leaders with the skills needed to manage teams in a digital age? What creative strategies can you employ to ready your workforce for the future? Should you be looking at benchmarking to work toward best practices as an industry?

LICENSE TO OPERATE

License to operate was named the biggest risk by 44% of those surveyed by EY and remains at the top of the list for another year. The disruption of social responsibility and broader stakeholder demands is intensifying, increasing expectations of shared value outcomes from mining projects. “The extended period of elections and resultant government changes has brought uncertainty to the political environment which has created volatility in the commodity markets,” explains Mitchell. “In addition, the sector is facing greater scrutiny from end consumers, demanding a transparent ethical supply chain as well as a lower carbon footprint. Shareholder activists are also driving many miners, particularly those with coal assets, to reshape their portfolios by either reconfiguring existing operations or executing divestments.”

Close collaboration with EKATO for the Çöpler Sulfide Expansion Project As for many other mineral processing projects, EKATO accompanied the Çöpler gold project over the last years. Already in the early design stages an intensive exchange and discussions between the end customer, engineering company and the equipment suppliers like EKATO took place. As the experience with other similar projects has shown in the past, this collaboration is increasingly limited to not just the equipment but to an extended scope of supply, which is appreciated by customers. In these cases, EKATO, with more than 85 years of experience in mixing technology and state-of-the-art testing equipment in its technical center, offers much more than just agitators. This additional scope can be quite extensive and cover all types of agitated applications in the plant flowsheet. For Anagold’s Çöpler Sulfide Expansion Project, EKATO designed and delivered agitators for all large agitated applications including the POX autoclaves‘ agitators. EKATO also performed several studies in its technical center. One of these series of tests was related to the optimum feed pipe locations and geometries in the first autoclave compartment. These tests in the model scale were then backed up by CFD (Computational Fluid Dynamics) studies which were carried out in-house as well. Other services included the assessment of slurry rheology data, supplied by other parties. The consideration of the appropriate slurry rheology is crucial for the proper operation of the agitators, especially for the large atmospheric tanks with capacities up to several thousand cubic meters. For this particular project, additional CFD simulations were prepared to double-check the designs of these tanks. EKATO’s capabilities also allow to extend this scope, provided during the design and construction phase, to the start-up and operation of the plant.

3D model of a world scale POX autoclave

Of course EKATO’s solutions are not limited to process related issues. The reliable mechanical design of the agitators, including the in-house manufactured mechanical seals and supply systems, ensures a maximum life time of the equipment with longest service intervals. This overall reliability has not only been proven in this particular project but in many other projects in mineral processing.

Hilscher worked on a silver mine 12 months from closure due to constantly declining grades. Ore sorting was investigated to get the grades back up. “We did the test programme, we got the samples and discovered that nine out of 10 of their rocks were below cut-off grade,” explains Hilscher. “But one out of 10 of their rocks was extremely valuable. So, it was a very easy sort. We could have used XRF, XRT, laser, any one of those would have worked, so we scanned the rock with a conservative approach only throwing away 60% of the rock to begin with.

In 2017 DRA Global was awarded the contract for the development of a port facility and associated infrastructure for the export of bauxite, by Alufer Mining in Guinea. The Alufer Bel Air Mine project was DRA’s first causeway development, which expanded the company’s exposure within the marine environment. Bel Air was expected to have an initial production rate of 5.5 million tonnes per annum and included a 22.5km haul road running over eight river crossings, an export facility with the ROM tip that feeds a 6500-tonne live capacity stockpile, and a causeway extending 1.4km into the Atlantic Ocean, where a barge load out berth was constructed.

DECEMBER 2019

The scope included all the necessary infrastructure to operate the facility: construction camp, wellfields, power generation, offices, laboratory, workshop and a bailey bridge across the Koundinde Work on the project commenced in January 2017 and was completed in August 2018 before commercial production was achieved within the first six months of operation. Alufer is on target to reach its annual production rate of 5.5 million wet tonnes by the end of 2019. DRA Global’s extensive material handling, earthworks and infrastructure design capabilities have contributed significantly to the success of the project.

designs, there are optimisation opportunities. Instead of sending all the tailings sand to a filter plant, you may have a two-stage cyclone plant first. The coarsest fraction is used for roads and earthworks, the fine fraction goes to the existing tailings pond (or co-disposal piles), and the mid-size material is filtered. This compromise reduces tailings pond sizes by two thirds while also removing most of the fines and clays that are so difficult to filter. “Of course, sensor sorting, DMS, and 114
