Metso’s latest innovation makes changing liners in VERTIMILL® vertical grinding mills safer and faster Metso has developed a solution to ease the maintenance of VERTIMILL® Grinding Mills. The innovative VERTIMILL® Liner Lifting Fixture speeds up the changing of the mill liners and makes it safer. Metso has been testing the tool at a customer site since June 2013 and it will be available for existing and future customers in early 2014.
T
he new VERTIMILL® Liner Lifting Fixture was designed to meet growing customer demand for a more efficient way to handle liner changing. As new, larger VERTIMILL® Grinding Mills with correspondingly larger and heavier liners have caught on, the traditional method of installing the screw liners with basic lifting tools has proven difficult and unsafe. “Our approach was to work backwards from what clients need and want so our design is unique in the way that all operational constraints are considered and will offer a flawless solution by combining Metso experience and customer feedback”, explains Clive Heath, Technical Development Manager, Life Cycle Services Metso Mining and Construction. “You cannot perform today’s tasks with yesterday’s methods and expect to be in business tomorrow”, he adds. “Providing added value for our customers through continual optimization of current practices is one of our main goals. This new method of VTM liner replacement is just one of those examples where Metso has developed an innovative solution to help its customers succeed”, says Simon Pelletier, Senior Vice President of Life Cycle Services, Metso Mining and Construction. Metso draws from more than 100 years of mill design and manufacturing expertise, and over three decades of successful VERTIMILL® Grinding Mill applications. Since its introduction in the late 1970s, close to 420 VERTIMILL® Grinding Mills have been sold worldwide. The high-capacity vertical grinding mill has proven to be a versatile tool that exhibits many advantages over traditional ball milling. In comparison to traditional ball mills, in fine and regrind applications, the VERTIMILL® mills can perform the same grind with 30% to 50% less energy and significantly lower grinding media consumption. The VERTIMILL® application range is also being extended into the coarse and secondary applications, creating more energy saving opportunities. Furthermore, the machine has fewer moving parts than a ball mill, translating into faster and cheaper installation, lower maintenance and operating costs. These features bring substantial savings for mining companies.

The Democratic Republic of Congo seeks to hike royalties Miners with sites under exploration could retain the 10-year period during which contract stability is guaranteed if they transform their licenses into exploitation permit within 2 years after the implementation of the new code. New mining project would be subjected to a 5 year stability clause. But Glencore,Randgold and AngloGold subsidiaries in Congo are pushing for the government to respect a current 10-year clause in the code, which would preclude any immediate change to royalties and copper and cobalt miners would consider a royalty increase to 3.5% if the country provides miners with enough power.

INVESTMENT
Copper investors advised to keep an eye on Zambia Amid predictions that the copper sector would remain buoyant this year from a pricing and project development perspective, professional services firm EY suggested that investors should keep a close eye on Zambia, as it was the largest copper producer in Africa.
“
While Zambia has large quantities of copper resources, it is also relatively stable, politically and in terms of its legislative framework. Recent initiatives by the Zambia government seem to indicate a willingness to create an environment of predictability and
12 | July-September 2014
transparency going forward. This potentially provides investor with a great deal of certainty, “said EY Africa advisory services mining and metal leader Mike Roy said. EY assurance director Louis Van Breda added that mineral-rich West African countries, such as Cote d’Ivoire, Ghana, Sierra Leone, Mali and Guinea Zambia is the largest copper had the potential producer on the continent to significantly expand their mining operations. He cautioned, however, that all growth forecasts for these countries depended on political, social and legislative stability. With regard to Southern Africabased projects, Roy and Van Breda cited Namibia as an important country to watch, not only because of its large uranium reserves but also because of its developing base metal mining operation, which focus on iron-ore and manganese. Further, Roy projected that there would be a slow upturn in the African mining sector this year and in potential consolidation among junior mining houses, owing to the juniors’ current inability to source additional capital.

“Would not be surprise to see capital flowing into the local mining sectors in the form of private equity funds,” he added. Roy also maintained that some of the private equity funding on offer. “I do not foresee the majors undertaking any significant new development this year, as most of them are recovering from a difficult 2013 and will remain cautious about investing large amounts of capital in new project,” he said. Roy also highlighted the Chinese and Indian demand for iron-ore and coal as a developing trend for mining stakeholders to take note of in 2014. Meanwhile, Roy and Van Breda agreed that Mineral Resources Minister Susan Shabangu’s assertion, during her Indaba keynote address, that beneficiation would not be forced on the mining industry was positive for mining companies, as it provided them with flexibility in their operations. “Minister Shabangu is well aware that investors and mining companies have been concerned about the prospects of forced beneficiation and the seemingly diktat fashion in which her Ministry was going about the beneficiation discussion process. It is interesting to note a more measured approach in the Minister’s address,” said Roy.

North Western Railway Project construction planned to take off in March 2014 - Kavindele
A
F • • • •
Construction of the US$1 billion joint venture North West Rail took off in this March 2014 and will be cardinal in resolving the transportation hurdles faced by mining companies in north western Zambia.
N
orth Western Rail Limited and Grindrod Limited have signed a joint venture agreement to construct the more than 580 kilometer rail line to link Zambia with Angola, after months of planning. North Western Rail Limited Executive Chairman Enoch Kavindele says the finalization of the agreement with Grindrod Limited is a breakthrough in resolving the transportation problems faced by mining companies-chiefly in north western Zambia. “It’s a great achievement to have the project finally took off,” says Kavindele. “We hope to start the construction of the first phase by March (2014),” Investing in African Mining which has drawn over 1,800 participants’ globally. The agreement has been cemented with Grindrod Limited under exclusive rights granted
14 | July-September 2014
to NWR by the Zambian government in July 2006. The partnership will allow the developers conclude a bankable feasibility study now under way. In recent years, Lumwana mine, a unit of Barrick Gold and Kansanshi Copper Mine, a subsidiary of First Quantum Minerals Limited, among others, has solely relied on roads to transport copper concentrates to refineries on the Copperbelt, leaving serious degradation of the road infrastructure. The railway facility, which has lacked in the area, will undoubtedly alleviate the wear and tear of the road network. The more than 100-year-old Zambia Railways Limited has no infrastructure in North Western Zambia and other areas of the country, a situation that has contributed to the rapid tear and wear of the road network because of maximized usage in the transportation of bulk material. Kavindele envisages that the agreement will reduce the toll on the road infrastructure in the north western province where mining companies are compelled to hire trucks to ferry their concentrates to copper refining facilities. It is envisaged by developers that the 590 kilometer railway project when completed will link Zambia with Angola up to Jimbe Port. The first 290km first phase of the railway project will run from Chingola to the Kansanshi, Lumwana and Kalumbila mines in north western Zambia, at an estimated capital cost of $489 million. The second phase, to gobble about $500m, will connect with the Benguela line on the ZambiaAngola border near Jimbe. This phase will open a direct corridor to Lobito. This railway link will allow landlocked Zambia to import oil directly from Angola and to stimulate further mining activity in the western copper belt region. KPMG’s infrastructure and major projects team have developed the project with NWR over the past one year and facilitated the closure of the deal.
Dave Rennie, the chief executive of the Grindrod Freight Services division, hopes the conclusion of the project will allow Grindrod to extract synergies from its existing investments in the north-south rail corridor and its port operations in Maputo, Richards Bay and Durban. The copperbelt straddled the border of northern Zambia and southern Democratic Republic of Congo and was one of the richest and most underdeveloped geological regions in Africa. The rail line venture, upon completion, will enable Lumwana and Kansanshi mines cut costs on transportation “The first locomotives will be ready to carry copper concentrate in 18 months,” Kavindele had earlier envisioned. Last year, the Government was forced to enact a law, introducing a toll-road system due to the heavy wear and tear on the infrastructure. This will help to raise the much needed resources to maintain the road infrastructure. Finance minister Alexander Chikwanda has in his 2014 budget set aside US$120 million to upgrade Zambia Railways Limited infrastructure and reduce the effect on roads. Grindrod Group of Companies, the Johannesburg Stock Exchange listed company has various subsidiaries, joint venture and associated companies in 37 countries worldwide. It has a labour force of more than 7 000 skilled and dedicated people. It views empowerment, transformation and education as an important aspect of its corporate responsibility. It operates Freight, Trading, Shipping and Financial Services – provides operating and marketing synergies locally and internationally in its pursuit of becoming a fully integrated freight, logistics and shipping service provider. Grindrod continues to invest in assets and opportunities across the four operating divisions with specific focus on dry bulk and bulk liquid commodities, containerised cargo and vehicles. It envisions remaining a dominant and profitable freight service provider, focusing on infrastructural development on the African continent-hence laying the ground for the development of the North West

New mining equipment to boost fight against silicosis XRD is the new buzz word in the CSIR mining research group’s corridors. This new piece of equipment, also known as the Bruker D8 Advance, is an advanced X-ray diffractometer that promises to speed up and improve the quality of the CSIR’s laboratory analysis of silica dust.
“
Respirable silica is a serious health concern in the gold mining industry,” says researcher Cecilia Pretorius. “Exposure to silica dust causes silicosis, a deadly lung disease, which is a major concern for the South African mining industry.” The XRD can analyse the phases or crystal forms of a material to determine the substances that are present in a specific sample. In
mining it is used to determine what proportion of a dust sample consists of quartz. “It is the quartz component of the silica dust that is the culprit,” says Pretorius. The Mine Health and Safety Council (MHSC) appointed the CSIR for two projects concerning the ultimate mitigation of Respirable silica dust. “The projects are part of a national initiative that
jointly set targets for the elimination of silicosis in South African mines by 2013,” Pretorius explains. In 2005, the MHSC appointed the CSIR for a five-year project to research the containment/ elimination of silicosis. “While research on dust exposure and control has been conducted for decades, the containment of silica particles have not yet been researched properly,” according to CSIR occupational hygienist and research coordinator, Tania van Dyk. “In addition, awareness about dust exposure and health effects is one of the priority areas for the MHSC silicosis control programme. Close collaboration is required with the dust measurement and dust control projects on silicosis elimination,” she says. The project consists of three parts, namely dust measurement and reporting, environmental engineering/dust control, and human resources training and management. The second MHSC project will determine a baseline for silica dust in the industry to establish the levels of dust present in mines and to monitor the implementation of control techniques. The CSIR has acquired the latest version of the D8 Advance to ensure improved efficiency

ENVIRONMENT
Diamond mining may threaten Namibian coastline The Benguela Current Commission (BCC), a multispectral intergovernmental initiative of Angola, Namibia and South Africa, could play a role in coordinating studies that monitor the impact of mining on the marine environment.
T
he BCC is responsible for coordinating the efforts of the three countries in addressing the Trans boundary environmental issues that affect the Benguela region. The commission has a mandate to use the best available scientific evidence to advise the governments on the best course of action to take. Trans boundary issues are those that affect one or more countries in the Benguela region, such as marine diamond mining, which is conducted in both Namibia and South Africa. Therefore, monitoring environmental impacts is one of the areas of interest for the BCC. For example, the commission would be in a position to advise the governments about the proximity of mining operations to sensitive areas or biodiversity hot spots. “We are coordinating a large mapping project, which aims to identify sensitive areas and potential protected areas across the Benguela Current Large Marine Ecosystem (BCLME),” says BCC executive secretary Dr Hashali Hamukuaya. The BCLME geo- graphically covers Angola, South Africa and Namibia. Near-shore and coastal diamond mining in the BCLME involves the discharge of tailings – generally sediments – into the marine environment. In the past, concerns have been raised about the impact of discharging these tailings into the marine environment, especially into the habitat of rock lobster. Hamukuaya highlights that the BCLME is one of the most productive marine ecosystems on earth and a globally significant centre for marine biodiversity. “It is also worth noting that Namibia has placed a moratorium on mining the seabed for phosphates, partly because of the closeness of the mining area to fishing activities and nursery areas for certain deepsea fish species,” he says. The BCC supports Namibia’s application of the precautionary principle, which stipu- lates that mining practices should not be undertaken if the consequences remain uncertain or if the action is potentially dangerous to the health of the environment. Coastline mining A 2006 study of the cumulative effects of tailings
20 | July-September 2014
from diamond mining, conducted by South African research organisation the Council for Scientific and Industrial Research (CSIR), found that fine sediment produced by simultaneous vessel- and land-based mining operations could have a cumulative negative effect on the environment. Although the study found that this effect would be minor, the cumulative effects of discharging course sediments could be more significant. Some of the southern Namibian mining operations are connected through littoral sand transport. As a result of this connectivity, mine sand discharges can potentially result in cumulative effects. The study provided several detailed recommendations for further monitoring and modelling, and suggested that mining companies have the opportunity to mitigate the effects of discharged sediment using appro- priate management processes. Moreover, the study found that discharging mine tailings at a littoral site that is exposed to waves will result in a more rapid dispersion of fine material than if the mine tailings were discharged at a wavesheltered site, which, in turn, will result in lower concentrations being experienced near the discharge point. The study recommended that mine modelling should be employed for mining companies to site fine and coarse sediment discharges relative to sensitive areas, such as power station water intakes and estuaries. Elevated concentrations of fine sediment should be limited to within a few hundred metres of the
discharge location. This provides a rough guideline for fine sediment discharges relative to sensitive areas and/or relative to existing fine sediment discharges. Mining companies could consider the potential discharge of mine tailings into mined-out areas. However, they should also consider the salinity of associated groundwater effects, as well as the composition of sediment, to avoid the formation of a bog containing excessive fine sediment, the study found. Mining companies could also consider the mechanical management of tailings through thickening or degrit processes, for example. Further, they could consider using bulldozers and dredging to aid the process of natural erosion and mitigate the retreat of accreted beaches. About the BCC The BCC promotes the sustainable management and protection of the BCLME and provides a platform for Angola, Namibia and South Africa to introduce an ecosystem approach to ocean governance. This means that, instead of managing living and nonliving resources at national level, the three countries can work together to tackle environmental challenges that impact on the marine environment at a continental level. The commission focuses on managing shared fish stocks, environmental monitoring, biodiversity and ecosystem health; mitigating pollution; reducing the impact of marine mining and oil and gas production; as well as capacity building.

Exploration and Mine Design Solutions The upcoming release of Micromine 2014
L
eading provider of software solutions and services to the global exploration and mining community, MICROMINE, provides mine operations with the technology required to drive productivity and cost efficiencies throughout the mining process. Founded in 1986, MICROMINE has spent the past 28 years introducing and further developing software solutions specific to the needs of exploration and mining companies worldwide. MICROMINE’s suite of software solutions cover the entire mining process, from geological exploration through to mine design and mine production. This unique offering allows clients to purchase all of their software from the one vendor. MICROMINE is currently preparing for the launch of Micromine 2014, the latest version of the company’s namesake exploration and mine design solution, Micromine. The application is due for release mid-2014. Micromine is a modular solution which allows the capture, management and interpretation of critical exploration and mining data. Micromine provides explorers an in-depth understand of a project so prospective regions can be targeted more accurately. Miners are provided easy-to-use modelling, estimation and design tools to simplify day-to-day design and production tasks. Micromine is renowned for its user-friendly and intuitive nature. Because of Micromine’s logical simplicity users can easily become proficient in the application andcomplete tasks quickly, increasing efficiencies. Micromine Product Manager, Daria Lvova, explains “Consistent with all MICROMINE releases, Micromine 2014 focuses on intuitive usability with enhanced workflow methodologies and logical processes. Significantly, Micromine 2014 closely follows the release of Micromine 2013, and includes many enhancements and new functionalities associated with the application’s mine design capabilities”. “Micromine is already a leader in the field within this area. The solution contains one of the only trueimplicit modellers. Released in Micromine 2013, Micromine’s Implicit Modelling module uses industrystandard radial basis (RBFs) to model grade shells, lithology boundaries, faults and surfaces. Wireframes extracted from the implicit model are readily displayed in Vizex, Micromine’s 3D environment, and are a valuable tool for finalising geological interpretations. Micromine offers simple methods for adding control

points (such as drillhole intersections) to create a more accurate fault model. It also provides support for trend information to produce models that better reflect the project area. Micromine 2014 contains a variety of new user benefits and improved, intuitive functionality associated with exploration, capability and performance, and mining. The application’s new features have been designed to further improve operational efficiencies and ease-of-use, and are highly relevant to both exploration and mining companies”. “I am confident that MICROMINE 2014 will be well-received by the international mining community. MICROMINE invests a significant percentage of annual revenue into research and development to ensure that our software solutions are constantly evolving and continue to exceed clients’ expectations”, Lvova concludes One area of development that is currently an area of focus is the integration between Micromine’s mine design tools and the HPGPS Machine Guidance System. Mine designs produced in Micromine, including blast projects, will be published directly out of the mine design package into the Pitram machine guidance system. Pitram is MICROMINE’s leading mine operations system. The integration will be two-way so actual as-completed project data will arrive directly to the mine design package as soon as the work is finished. This innovation will transfer live project progress information back to the mine engineer’s desktop. NEW FEATURES IN MICROMINE 2014 64-bit application The largest single change is the conversion of Micromine to a full 64-bit application, building on the hybrid 32/64-bit framework of our last few releases and allowing our clients to work with larger data than ever before. Micromine was already good
CAD enhancements Our engineering and design clients gain a number of major CAD enhancements including new snap modes, the ability to mirror strings, and a dynamic input mode that allows them to enter specific numbers (such as a gradient or distance) in the middle of a graphical editing session. We’ve also extensively enhanced our pit design tools with new road and switchback options, along with some brand new road design tools. Graphic and statistics We’ve completely rewritten many of our graphing and statistical functions, giving them much better graphics and more interactivity. The changes are so extensive that they are effectively new features. Along with these we’ve added brand new features like boxand-whisker plots and a new statistical summary. We looked at clients’ statistical workflows and ensured that users can easily produce what they need with minimal effort. Although everyone will benefit from this improved workflow, it is especially important for exploration and resource geologists who use statistics on a daily basis. Our Steronet display has undergone a similar rewrite to make it much more visual and capable, along with adding a number of analysis options for poles and planes. These new features are only the beginning; we plan to release more stats and graph updates in future versions. Graphic and statistics Geologists benefit from two new Vizex (Visual Explorer) fence diagram options: a 3D fence section, which produces a traditional fence section using segments that may be drawn anywhere within the display, and a drillhole fence, with segments that snap to drillhole collars. All holes in a drillhole fence display are drawn vertically, making it ideal for seam correlation. For cartographic presentation we’ve enhanced our fill (hatch) patterns by adding support for rotation and automatic alignment to the drillhole orientation, along with adding enhanced scaling options to our points display.

COUNTRY FOCUS - NAMIBIA
Exploring Namibia’s rich uranium reserves
Edw
Having been involved in the Namibian mining industry since the early 2000s, advancedstage Canadian explorer Forsys Metals says that it continues to see growth potential in the region and describes Namibia as a mining-friendly and politically stable country.
Valencia Uranium Mine
“
We have a long history with the mining industry in Namibia and have been in the country for several years, primarily focused on advancing our developmentstage uranium project, says Forsys Metals CEO Marcel Hilmer, adding that the company also has a small stake in gold exploration. The company is currently developing the Norasa uranium project, comprising the Valencia main uranium deposit, satellite pits and Namibplaas deposits. The Valencia deposit is situated about 80 km from the coastal town of Swakopmund. The Norasa project spans a 35 km strike to the Rössing uranium mine, which has been in production for over 30 years and is majority- owned by multinational diversified mining major Rio Tinto. The project is also 50 km north of the Langer Heinrich uranium mine, owned by ASX-listed Paladin Energy. Hilmer believes that what sets Norasa’s Valencia mine apart from the other major uranium exploration and development projects in Namibia is that it is fully
24 | July-September 2014
permitted, including all environmental approvals. In August 2008, the Namibian government issued the company with a 25-year mining licence. Construction of the Valencia mine is set to start in early 2015, while plant commissioning is expected to be under way by mid-2016. Mining at Norasa will start in early 2016 to prepare pit benches and open mining faces. In March, Forsys Metals updated its initial scoping studies, as well as its pit improvement and metallurgical, environmental and economic studies for the development of Norasa. The company also released an updated National Instrument 43-101-compliant technical report to prefeasibility level. Hilmer tells Mining Suppliers Guide that the uranium mined at Norasa is intended for export, adding that there are no beneficiation facilities in Namibia. “However, if the government moves forward with its intentions to beneficiate, we will be investing in this to keep some of the uranium in the country,” he notes.
The Norasa project supports a 13-year mine life at the proposed production rate, which is 2 305 t/y. Meanwhile, in the second quarter of 2010, an important 26 km road was completed, joining the Valencia mine site to the main highway. Some internal service roads have also been constructed since then. Construction of power infrastructure, in conjunction with Namibian power utility NamPower, is also under way and Forsys Metals has entered into a memorandum of understanding with Namibian water utility NamWater to obtain the water required for the mine’s construction and production phases. Given the advanced stage of the project, its location, and its infrastructure agreements, as well as Namibia’s politically stable environment and its record of supporting the successful development of uranium resources, Hilmer says that the Norasa development presents a rare opportunity for investors to participate in what could potentially be one of the next biggest uranium-producing mines in the near future. Expansion Potential Based on current knowledge and exploration success to date, Forsys Metals believes there is potential for future expansion at the Valencia uranium reserve base. Additional space below the currently defined Valencia pit, which is 350 m × 300 m wide, would also enable the company to expand downwards by a few benches. “Several holes in the 2009 drill programme were drilled roughly 20 m beyond the current pit bottom, which is 380 m from surface,” highlights Hilmer.

NamPower plans to construct its own 800 MW gas power station, in cooperation with a Zambian power company. This will all contribute to the eventual operation of Forsys Metals’ Norasa project. A central office and administration complex for the mine will also be constructed, and a semipermanent village will be established 8 km from the Norasa plant.
The company’s expectation of additional resource expansion below an elevation of 350 m is further reinforced by one deep drill hole, drilled in 2008, which encountered ore- grade mineralisation down to a depth of 470 m. Water and Power Supply Meanwhile, short- and medium-term supply of water from French public multinational Areva’s desalination plant, as well as NamWater’s own desalination plant, will be used to provide the Norasa project with its long-term water requirements of up to 20-million cubic metres a year. Further, Namibia signed a 122 MW electricity import agreement with Mozambique in 2013, while

Namibia-Focused Forsys Metals began investing in Namibia in around 2008. “The company decided to invest in Namibia because of its vast potential. At the time, we were able to get involved in the acquisition of exclusive prospecting rights in Namibia for uranium projects and we took up that opportunity,” says Hilmer. Today, Namibia is still showing great potential as a preferred African mining investment. “I also believe that Namibia is one of the African countries that is showing the greatest potential, owing to its established democracy that supports fair mining practices, as well as the abundance of resources available in the country, especially uranium,” highlights Hilmer. He adds, however, that while Namibia is one
of the best countries to work in, compared with other countries in Africa, certain challenges remain. “Namibia covers a large area but has a small population. Therefore, there are potential infrastructure issues, the biggest of which relate to water and power infrastructure, which the government is attempting to address,” says Hilmer. Investors have also identified Namibia’s lack of road and rail infrastructure as potential challenges currently facing the country. Nevertheless, Forsys Metals says it does not plan on expanding into other African regions just yet. “We are focusing on furthering the Norasa project, which would be the sixth-largest uranium producer in the world if it were operational. We are adopting an extremely focused strategy with Norasa, rather than dividing our attention between Norasa and other projects,” says Hilmer. Meanwhile, the availability of skills in a country with as small a population as Namibia has concerned some investors. However, Forsys Metals mentions that it prioritises hiring native Namibians wherever possible. “About 90% of our staff are Namibian, with one or two individuals who are not locals. This is a deliberate strategy to ensure the transfer of skills,” says Hilmer. The company also invests in sponsoring university bursaries. “We have sponsored up to five individuals at a time, helping them work their way through university in departments such as geology,” says Hilmer, adding that the goal of the company is to qualify university students who will ultimately be employed at Forsys Metals. Hilmer highlights that between N$20 000 and N$50 000 is spent on student bursaries and training each year. “We not only pay for study fees, but also for books and university accommodation,” he says. About Forsys Metals Forsys Metals has several assets being developed in Namibia. The company has the capability to capitalise on attractive mid- and long-term uranium sector dynamics by focusing on enhancing the wholly owned Norasa uranium project. Through its extensive exploration and technical programmes, Forsys has reported substantial uranium resources.

Indian Multinational Stakes US$50 Million for Tanzanian Mine As the exploration and search for minerals continues on the African continent, several multinational companies have shown eagerness to maximize on this mineral potential in the 54-member states.
A
mong the countries that have in recent months attracted scores of multinational companies is Tanzania, courted by National Mineral Development Corporation (NMDC)
of India. In its quest to expand its business beyond Asia, India’s largest iron ore miner is ready to develop the Bulyang’Ombe mining project in Tanzania at an estimated cost of US$50m. The intention comes nearly 18 months after the Indian company submitted their feasibility report to the Tanzanian authorities for consideration of its intentions to invest in the sisal-rich East African nation. According to local media reports, NMDC has devised a short-term strategy, which includes setting up of a small-scale mining and processing plant for its Tanzanian gold project. The project is estimated to have gold deposits of four tons. NMDC intends to develop the gold project through a Mine Development cum Operator (MDO). NMDC had carried out gold exploration in the southern region of Lake Victoria, north-western part of Tanzania, during 2000 to 2003 delineating promising targets in Siga Hill area (Kahama district) and Bulyang’Ombe area (Nzega district). Tanzania’s Ministry of Energy and Minerals had granted NMDC four mining leases at the Bulyang’Ombe gold prospect in 2012, having a total area of 38.83 sq km for 10 years. Apart from iron ore, NMDC also has interests in diamond mining. Its production of the precious material in the last fiscal year stood at 37,007 carats. NMDC is India’s only diamond producer operating from its Panna mine in Madhya Pradesh. The company produced 30.18 million tons iron ore and sold 30.50 metric tons of the key steelmaking raw materials in the last fiscal year. Background: The NMDC Limited (BSE: 526371, NSE: NMDC) is a wholly owned, state-controlled mineral producer of the Government of India. It is also under the administrative control of the Ministry of Steel. It is involved in the exploration of iron, ore, copper, rock, phosphate, limestone, dolomite, gypsum, bentonite, magnesite, diamond,
28 | July-September 2014
tin,tungsten and graphite among other minerals. It is India’s largest iron ore producer and exporter, producing about 30 million tons of ore from three fully mechanised mines in Chhatisgarh and Karnataka. It also operates the only mechanised diamond mine in the country at Panna in Madhya Pradesh. NMDC Limited is also diversifying into other raw materials for steel industry like low silica limestone. Production of Dead Burnt magnesite and further value addition is under study through its subsidiary J K Mineral Development Corporation Limited. The company has taken over a Silica Sand mining and beneficiaton project from Uttar Pradesh State Mineral Development Corporation Ltd., The plant has been designed to produce high purity beneficiatedsilica sand of around 300,000 tonnes per year which is a raw material for production of float/ sheet glass. With a view to capture the opportunities now available following the Navaratna recognition and its expertise in the field of mineral exploration and
mining, NMDC is venturing into development of high value minerals like gold and diamond, as joint ventures in some African countries. A Memorandum of Understanding has been signed between NMDC, Indian Rare Earths Limited, (IRE) and Andhra Pradesh Mineral Development Corporation to establish a joint venture for the development of Bheemunipatnam Beach Sand. The project envisages mining of beach sands, setting up of mineral separation plant for Ilmenite concentrate and a downstream value addition plant for conversion of Ilmenite into synthetic Rutile/TiO2 slag/TiO2 pigment with pig iron as by-product. NMDC is setting up a 3 MTPA capacity Greenfield Integrated Steel Plant in Nagarnar, located 16 km from Jagdalpur, with an estimated outlay of Rs 18,000 core. The land for the plant has already been acquired as of August 2010 and, as of February 2012, 9 major packages and certain auxiliaries packages of the steel plant have already been awarded to internationally acclaimed companies at a cost of around Rs.11,000 core.

INVESTMENT
Ivanhoe shares hit by funding uncertainty for DRC copper projects Africa-focused project developer Ivanhoe Mines said on Thursday that it did not have enough money to meet certain objectives at its two base metals projects in the Democratic Republic of Congo (DRC), unless it received a significant cash injection before the end of the current quarter.
T
he project developer said that it had available consolidated working capital of about $149.8-million at the end of March, compared with $201.7-million at December 31, adding that it would focus the bulk of the capital on pushing forward with the bulk-sampling shaft at the Platreef project, in South Africa’s Limpopo province. The company, founded by billionaire mining legend Robert Friedland, said it had $145.2-million available to spend on the Platreef project, which would sustain it through to early next year, and $4.6-million for the DRC projects, which is insufficient to start the underground mine-access decline at the 95%-owned Kamoa project and implement an underground drilling programme at the 68%-owned Kipushi project. “The company does not have sufficient funds to meet these objectives at Kamoa or Kipushi without further funding by the end of the second quarter. Any future working capital deficiency is expected to
30 | July-September 2014
be remedied through a debt or equity financing. “The company’s access to financing is always uncertain and there can be no assurance that additional funding will be available to the company in the near future,” Ivanhoe said in a statement. Ivanhoe said that in order to help realise the potential value of its world-scale African projects, it is looking at a number of potentially significant corporate and project-level options, including a corporate reorganisation; project spin-offs (including potentially separating its South African platinum assets and its DRC copper and zinc assets into separately listed public companies); sales or joint ventures; project- or corporate-level debt and/ or equity investments (including interim financing); and additional and/or alternative stock-exchange listings for certain of the company’s projects. Last year, Ivanhoe raised C$108-million to spend on its DRC projects, and Friedland himself subscribed for C$25-million of the offering. Ivanhoe in November said it would need
$1.4-billion to bring the Kamoa project on line, while a March preliminary economic assessment found it would need about $1.7-billion to bring the 90%-owned Platreef project to production. A Japanese consortium comprising Itochu Corporation; Japan Oil, Gas and Metals National Corporation and JGC Corporation owns the other 10% of the project. The news sent its TSX-listed shares falling by as much as C$0.31 apiece on Thursday, before regaining some ground to close at C$1.51 apiece. Friedland made a name in 1996 by selling a thenundeveloped Canadian nickel/copper project called Voisey’s Bay for C$4.3-billion. He solidified his near-legendary status within the mining industry with Ivanhoe Mines, a vehicle he used to promote and build the goliath Oyu Tolgoi copper/gold mine in Mongolia. In 2012, mining giant Rio Tinto acquired a majority interest in Ivanhoe, which is now called Turquoise Hill Resources. That deal allowed Friedland to concentrate on Ivanplats (which had subsequently been renamed Ivanhoe Mines), taking it public in 2012 in one of the most closely followed initial public offerings of the year. The partial offering raised about C$300million. STAFF MOVEMENTS Earlier this month, Ivanhoe appointed senior South African mining executive Mark Farren as the company’s executive VP of operations, effective from June 15. He would be tasked with responsibility for the various engineering and development activities at the Kamoa, Kipushi and Platreef projects. He would also assume the main duties presently performed by COO Michael Gray, who would retire from his day-to-day role with Ivanhoe at the end of June. Gray would continue to advise the company on mining-related matters as a consultant. Executive VP and chief development officer Steve Garcia, who helped establish the foundations for Ivanhoe’s corporate growth and project development, resigned from the company at the end of April.

PROJECTS
Projects in Namibia to boost economy The Namibian mining industry is set for substantial growth in the future, with a number of projects at various stages of development in progress.
E
arlier this year it was reported that international gold miner B2Gold’s Otjikoto gold project had begun construction. A feasibility study on the project, located about 300 km north of Namibia’s capital city Windhoek, demonstrated the robust economics of the project. The mine plan is based on probable mineral reserves of 29.4-million tons, grading 1.42 g/t for 1.341-million ounces of gold at a stripping ratio of 5.59:1 to be mined over an initial 12-year period. Average yearly production for the first five years is estimated at 141 000 oz/y of gold. The gold project will be developed as an open pit mine, with run-of-mine ore trucked to the plant, crushed and then treated in a grinding circuit using conventional semi- autogenously grinding and ball mills, and a carbon-in-leach recovery process. Construction is scheduled for completion in the fourth quarter of 2014, when mill production will begin, with all necessary government permits and licences received. An aggressive exploration drilling programme continues on the success of the high-grade Wolfshag zone, which was discovered in late 2012 and is adjacent to the planned Otjikoto pit. These positive results indicate signifi- cant exploration upside and the potential to outline additional resources, which could lead to the expansion of throughput capacity and an increase in average yearly gold production. It was not stated whether the project was on time

and within budget. Meanwhile, it was also reported that mining and smelting company Weatherly International is undertaking the reopening of the Old Matchless copper mine. The Old Matchless mine is located about 2 km east of Weatherly’s current Matchless mining operations. The mine operated until 1983, when it was closed by international gold mining giant Newmont, owing to strategic and economic conditions at the time. The non-Joint Ore Reserves Committee- (Jorc) compliant historical reserve for the Old Matchless mine is 812 639 t at 2.4% copper, containing 19 506 t of contained copper. The development of the mine will supply additional high-grade ore feed to the Otjihase concentrator and will increase production by more than 3 000 t/y of copper. The proposed mine plan envisages the extraction of 748 484 t of ore at 2.38% copper, recovering 16 387 t of copper metal contained in concentrates. The current mining plan involves the
development of a decline from surface to access the three previously mined ore shoots, which are open at depth. Ore extraction is planned using mechanised and hand-held cut-and-fill methods. The old level accesses and the hoisting shaft will be used for ventilation exhaust, dewatering and secondary egress. The initial capital cost of the development is estimated at R68.4-million. Production will start within 13 months of the start of the decline, with full production achieved within 24 months. Prepara- tory work is expected to start soon. It was not stated whether the project was within budget and on time. A subject of much controversy is the Sandpiper phosphate project being imple- mented by phosphate miner Namibian Marine Phosphate – a joint venture between phosphate company Minemakers (42.5%), Union Resources (42.5%) and Namibian investment company Tungeni Investments (15%). Late last year it was reported that the project tenements lie in waters about 60 km off the coast of

Vivo Energy currently supplies three of the five largest mines in Namibia
Namibia and cover a combined area of about 7 000 km2 in the regional phosphate-enriched province to the south of Walvis Bay, in water depths of between 180 m and 300 m. The project has total Jorc-compliant measured and indicated resources of 226.8-million tons at 20.2% phosphorus pent oxide (P2O5). A feasibility study has confirmed Sandpiper as technically and economically feasible and envisages steady-state production of three-million tons a year of P2O5 concentrate product (rock phosphate), grading 27.5% to 28% P2O5 over an initial mine life of 20 years, including a two-year ramp-up period. It is intended that dredging of the seafloor sediments will be achieved with a large-capacity trailing suction hopper dredge, using existing technology. Capital costs to first production for the three-million-ton operation are estimated at $326.3-million. This estimate excludes the potential capital cost of a small reverse-osmosis desalination plant, which may need to be constructed early in the mine life, the estimate of which is currently being refined. Following a final investment decision and securing financing for the project, the estimated construction and commissioning period is 24 months. A number of key activities remain ongoing, including the construction of the extended dredge arm by Belgian construction company Jan De Nul to allow dredging at water depths of 225 m; capi- tal cost optimisation; final front-end engineering design; negotiation of contracts for dredging, engineering,

procurement and construction management and key staff positions; continued product marketing to secure offtake agreements; and the financing of the project. Further, ASX- and TSX-listed Bannerman Resources, which owns 80% of the Etango uranium project (formerly Goanikontes), in Erongo, aims to proceed with the help of a development partner. The Etango project has measured, and indicated, resources of 336.2-million tons at 201 parts per million (ppm) for 148.8- million pounds of uranium oxide (U3O8) and an inferred resource of 164.6-million tons at 176 ppm for 63.9-million pounds of U3O8. A definitive feasibility study (DFS) has upped expected output at Etango by some 22%, after increasing the plant size from 15-million tons to 20-million tons a year. Production is expected to be between seven- and nine-million pounds of U3O8 a year for the first five years and between six- and eight-million pounds of U3O8 a year thereafter, for a minimum mine life of 16 years, which would place Etango among the world’s top ten uranium-only mining operations. Envisioned is a conventional openpit mining operation, which will use 550 t hydraulic back-hoe excavators and 220 t diesel/electric haul trucks. Drilling and blasting will be conducted on 12 m benches and mining on 4 m to 4.5 m flitches to reduce ore dilution. With this configuration, the mining rate is scheduled at a maximum 100-million tons a year. The DFS has also identified Etango mineralisation to be most suitable for heap leaching.
Further, significant upside exists at Etango through the potential conversion of existing inferred resources, as well as through new drilling programmes now under way for a targeted mine life of over 20 years. Preproduction capital is estimated at $870-million. Bannerman has started a resource expansion drilling programme to add new mineral resources and extend the mine life beyond 20 years. The company will also lodge the DFS and its environmental- and social-impact assessments, as well as the environmental and social management plan with the relevant Namibian authorities in support of the existing licence application.

INVESTMENT
SA investment in DRC opencast operations The Democratic Republic of Congo (DRC) is potentially one of the richest mining countries in Africa, based on its vast copper, cobalt and diamond resources, says mining equipment manufacturer VR Steel, which extended its services to the country last year.
V
R Steel MD John van Reenen told Mining Suppliers Guide that the company started supplying opencast mining equipment to global diversified natural resources company Glencore, Xstrata subsidiary Katanga Mining’s DRC copper and cobalt project in the second quarter of 2013. The contract comprises two orders to date, totalling about R7-million. “It seems that the DRC has huge growth potential for the opencast mining sector and, therefore, for VR Steel,” he says. Van Reenen predicts that VR Steel will supply Glencore Xstrata and other miners in the area with more products in the future. He highlights that the south of the DRC has an abundance of mines, adding that VR Steel recently began supplying equipment to one of the mines in the area. “Hopefully, as VR Steel becomes known in the area, more mines will use VR Steel products,” he says.
Challenges
Van Reenen highlights logistics as one of the major problems facing VR Steel in supplying equipment to the Katanga project, owing to the mine sites often being located in remote areas without adequate road infrastructure. “Transporting products is difficult, as they need to be transported in parts and then reassembled on site. “Further, skilled staff such as welders is needed in the DRC to assemble the products,” he says, adding that this process can also be quite time consuming. Meanwhile, Van Reenen also highlights that mining companies in South Africa are hesitant to spend money, owing to ongoing strike activity, which has resulted in mines losing a significant amount of money in operations. “While mining companies are holding back on spending because commodity prices are dropping, a lot of companies are also awaiting the outcome of the platinum strike negotiations, during which the final settlement figures will be determined.” He adds that, should the platinum mines concede as much as 10% to the mineworkers’ wage increase

demands, other commodity mines can expect similar demands from their own staff, thereby potentially causing financial problems throughout the entire mining sector.
Technology
Van Reenen highlights that VR Steel’s key differentiator is its wealth of engineering expertise. “We have a group of engineers who are world leaders in their field,” he says, adding that the company’s engineers have received praise from other international engineers who attended the MinExpo Mining Show in Las Vegas, US, in 2012. Van Reenen notes that the company is continuously upgrading its software to ensure it remains at the cutting edge of engineering technology. “We constantly compare our standards with international standards as a means of keeping up to date.” He told Mining Suppliers Guide that a German software supplier to the company has highlighted VR Steel as a success story and an advertising platform to promote its services to other mining companies. Van Reenen further mentions that South Africa ranks among the top in the world when it comes to innovative design in the mining sector. “South Africa sits highly among the world’s best. Our defence industry saw the development of many highly trained engineers, who have since transferred their skills into other sectors, such as mining and machinery.” He also highlights South Africa’s significant technology base, describing it as “more than the size of the country justifies”. Moreover, Van Reenen is positive about the number of students aiming to pursue a career in engineering. “With the South African government’s focus on maths and science in schools, many students are regarding these two subjects as vital and key to being accepted at university.” He adds that VR Steel supports its staff who wants to complete their honours, masters or doctoral degrees. “We currently have one staff member completing a doctorate, for which the company is paying,” says Van Reenen, further highlighting that the company offers bursaries to several students at local universities, including the University of the
Witwatersrand.
Growth Potential
Van Reenen says the opencast mining industry in South Africa is fairly stagnant, while other parts of Africa are showing greater growth potential in the sector. “Namibia, Mozambique, Zambia and the DRC are showing great mining potential, with VR Steel concentrating on Zambia and the DRC,” says Van Reenen. He also highlights Botswana as showing growth potential, owing to its diamond and coal resources. “We expect that Botswana will become a big player in the mining industry in the next ten years,” says Van Reenen.
About VR Steel
VR Steel started doing business in 1992 as a specialist steel distributor and service centre. The company produced the world’s first fabricated dragline bucket in 1994. The VR dragline bucket was launched in 2004, which was followed in 2006 by the VR rope shovel dipper and in 2007 by the VR hydraulic shovel bucket, the VR excavator bucket and the VR offhighway truck body. VR Steel is the only company in the world that designs, manufactures, sells and repairs all loading tools and truck bodies. By operating a maintenance workshop, the company has first-hand knowledge of the types of repairs that are frequently required. These problems are handed to the design engineering department to eliminate or reduce these problems, giving products a longer life. Products are manufactured at the company’s 12 000 m2 factory, in Alberton. The company also has a factory in Middelburg, where maintenance on dragline buckets is performed, and is considering opening regional workshops throughout the country. Van Reenen told Mining Suppliers Guide that the VR Steel truck bodies currently show the most success in the market, as they are designed to decrease cost and optimise performance, thereby enabling mining companies to produce at the lowest possible operating cost per ton.

Chilean mine expert tips Zambia on ‘attaining top copper producer’ Consistency in policies coupled with dialogue among players in the mining industry has sustained Chile’s reputation as the global top copper producer, which if emulated, Zambia can compete as world’s leader too, an expert says.

However, inspite of Chile’s reputation, there are still several other countries with significant operations, including neighboring Peru, as well as China, the United States and Russia that have shown resilience, according to the latest compilation of the top 10 countries in the world.

four months, according to data from the Zambian treasury,. However, Chile’s mine production hit a record 5,700,000 tons produced last year, up from 5,430,000 tons recorded two years ago. Copper is Chile’s mainstay, representing 20 percent of the country’s Gross Domestic Product. It accounts for 60 percent of the country’s exports. With help from copper revenue, the country’s economy is expanding threefold recording six percent annually; it also credits the industry with the country’s low rates of inflation and curbs unemployment, the US journal adds. China is rated second- globally with 1,650,000 tons mines last year-less than half of Chile’s outturn. China’s output rose from 1,530,000 tons in 2012 produced by the world’s largest consumer of the red metal, although new production sites are abound which will see the far East Asian state compete with Chile. Additionally, importing raw copper concentrate to China is costly, causing domestic smelting operations to begin to rise. Peru, is

rated third in the world with outturn of 1,300,000 produced last year, though not moved much from that recorded in 2012, the US journal adds. However Peru’s mine production, according to data, could rise as much as 10 percent in 2014, with that country’s energy and mines minister, Jorge Merino, projecting a 17-percent increase in copper production alone as the result of several new projects set to open in the year ahead. With prospects abound, Peru expects more foreign investment into its mining sector as a result of these projects. The United States, another emerging force in the production of the red metal is rated fourth having mined 1,220,000 tons last year up slightly from its figure of 1,170,000 tons in 2012, according to MINING.Com. This increase came despite a catastrophic landslide at Utah’s Bingham Canyon mine in early 2013; the incident which caused it to cease production for an extended period of time. The
total copper production in the US is worth more than $1 billion. Australia is rated fifth with levels estimated at 990,000 tons produced last year, marking an increase from 958,000 tons in 2012, according to Geoscience Australia, a government agency. Most of the copper resources in the country are located in Queensland and South Australia, though there are resources in each state and in the Northern Territory as well. Most of the country’s production is centered in the Mount Isa region in Queensland and the Olympic Dam mine in South Australia, the agency adds. Russia is rated sixth at 930,000 tons outturn last year up from the 883,000 tons it produced in 2012, according to NASDAQ. Russia has about 10 percent of the world’s copper reserves, and that the deposits are located primarily in Siberia and the Urals. The vast majority of Russian copper projects are in remote regions, away from population and infrastructure, which makes mining operations relatively difficult. Additionally, the country has laws restricting the amount of foreign investment in its mineral reserves. Inspite of the civil strife afflicting the 42 million populated and Africa’s mineral endowed Democratic Republic of the Congo; the country is rated seventh after hoisting 900,000 tons last year, a significant rise from the 600,000 tons produced in the country in 2012. The International Monetary Fund believes this level of production may spur the country’s economic growth to the tune of 8.7 percent in 2014, reports from Bloomberg news say. In 2012, the mining industry comprised more than 15 percent of the Congo’s gross domestic product, the news outlet notes. Zambia is eighth at 830,000 tons last year, rising from 690,000 tons a year earlier. However, last year saw the emerging of several new copper projects begin in Zambia, which in turn boosted production of the red metal by 21 percent in the first 11 months of the year, The Wall Street Journal can attest. “We are at a level where most copper projects that have been in the pipeline a few years back are coming on stream,” Fredrick Bantubonse, an independent metals analyst based in Zambia, told the Journal. Canada is ninth with output of 630,000 tons recorded last year, up from 579,000 tons recorded a year earlier, according to compilations by Natural Resources of Canada. It however, notes that copper volume and value both increased despite decreases in the metal’s price throughout the year. This is chiefly on account of a rise to new mine openings by Glencore Xstrata (LSE:GLEN) and Hudbay Minerals (TSX:HBM). Mexico is 10th with 480,000 tons, a slight increase from that of 2012 which accounted for 440,000 tones. Mexico forecasts increases in copper production over the next two years, according to Bloomberg news, although copper prices on the global metal market will be major determinants for that to occur.

Gemfields raises $33.5M from inaugural auction of mozambique rubies Gemfields plc has raised US$33.5m in Singapore from an inaugural auction of rubies from its new mine in Mozambique.
T
he auction was held in Singapore from June 12-17, 2014 and comprised high and low quality ruby and corundum extracted by Montepuez Ruby Mining Limitada, in which Gemfields has a 75 % interest, from the Montepuez ruby deposit in Mozambique. The availability of rough rubies, via Gemfields’ highly regarded auction platform, generated considerable market excitement, underpinning robust global demand. A total of 55 companies placed bids. Of the 62 lots offered, 57 were sold, representing approximately 91 % of the market value of the lots offered. In carat terms, the auction saw 2.03 million carats of ruby and corundum placed on offer, of which 1.82 million carats were sold (representing 90 % by weight), generating gross auction revenues of US$33.5 million. The auction yielded an overall average value of USD 18.43 per carat. Cumulative costs incurred at Montepuez to date (including acquisition cost, capital expenditure and operating costs) stand at approximately US$34 million in total. A considerable number of auction participants were attending a Gemfields auction for the first time. Most were from or closely associated with Thailand, which has a deep and long-standing relationship with the ruby trade. In an important development for the coloured gemstone industry as a whole, buyers from various other locations, including New York, Jaipur, Germany and Israel (many of whom have previously attended Gemfields’ emerald auctions), featured significantly at the Singapore ruby auction. This cross-pollination of clients and gemstone specialists is expected to further Gemfields’ vision for growth and development of the coloured gemstone sector internationally. Gemfields used the expertise derived from its development of a pioneering and proprietary rough emerald grading system at the Kagem emerald mine to assist in the development of a ‘first-of-a-kind’ comprehensive grading and sorting framework for rough rubies, and which was successfully utilised and received much acclaim from all of the participants attending the auction. Prior to the auction, Gemfields also investigated and tested various downstream ruby and corundum enhancement processes for rough gemstones, including heat treatment. These yielded encouraging results, improving the aesthetics of the rough material at a reasonable cost. Consequently, Gemfields offered both untreated and treated rough gemstones at the auction with any treated lots being offered on a fully disclosed basis. Gemfields announced the proposed acquisition

Completion of the acquisition, together with the issuance of 25-year licences, was announced on February 27, 2012. The extraction of ruby and corundum as part of the ongoing bulk-sampling program began in November 2012. At March 31, 2014, when Gemfields last provided a quarterly production update, total ruby and corundum extracted at Montepuez since the commencement of bulk sampling stood at 8.2 million carats. A cumulative total of approximately US$34 million has been spent at Montepuez to date (comprising the acquisition cost as well as capex and opex since inception). Ian Harebottle, CEO of Gemfields, commented: “We are naturally delighted to announce the stellar results of our first auction of rubies and corundum from Montepuez in Mozambique. The extension of our transparent and well-regarded auction platform into the ruby trade has been very well received by the market, with an expanded customer base now having access to reliably supplied and consistently graded rough emeralds, beryl, rubies and corundum.

as a standard offering. The Sentient is also available with Fire Patrol capabilities. Distinguished by its bright red seal, the Fire Patrol Sentient is inserted into outstations located in specific areas underground, where it records date, time, gas and humidity measurements. A downloading network configuration is capable of gathering information from up to 500 sentient units in a matter of minutes. All
this equipment is connected via a network to a Sentient downloading server, where specialised software enables various reports to be generated, such as detailed information on gas detected in the underground environment, peak values, TWA values, pre-shift tested values, calibration reports and “no movement reports”. Sentient software is web-based, making it possible to email these reports to relevant personnel automatically. The low maintenance Sentient has no buttons — instead an innovative “tap” sensor ensures that the instrument remains watertight. Another unique feature is a “drop protection” capability that automatically switches off the sensor if the instrument is dropped, reducing possible maintenance time and costs. Booyco Electronics is a single source market leader that supplies quality specialised electronic safety equipment, including collision intervention systems. Its range of reliable accurate warning, locating and monitoring systems is engineered to operate in the harsh African conditions.

World Bank to launch $1bn African resource mapping fund Global lender, World Bank plans to launch a $1-billion fund before the end of this year for mapping Africa’s minerals resources and ensures the continent benefits from its natural wealth, a senior Bank Official says.
T
he launch planned for July 2014 will be used to map the mineral resources of Africa using satellites and airborne surveys to fill geological gaps across the continent where a lack of adequate data hampers mining investments, says Bank’s senior manager at the World Bank’s mining unit, Paulo de Sa. The Bretton Woods institute has committed $200-million to the five-year fund, and was recently meeting with mining companies and governments from sub-Saharan Africa who have expressed interest, Paulo de Sa told Reuters recently. “Times are tough, so the mining companies are counting their pennies, but there is a lot of interest because it is exactly when commodity prices are low and the companies are reducing their investment budgets that having the information to guide their priorities is valuable,” De Sa had met with 10 mining companies on the side-lines of an African mining conference, including Rio Tinto and Ivanhoe Mines, who were interested in the fund. Initially targeting southern and eastern Africa, De Sa said the fund would aim to collate existing data onto a single, digital platform that would be accessible to the public. African governments could benefit by being able to negotiate better deals when handing concessions to mining companies- besides helping to guide exploration investment, De Sa said. “If they know what they have in their territory, they are in a better position to fine-tune and calibrate the fiscal regime and mining laws,” When Mozambique, for example, privatised its giant Moatize coal mine, it did not know the true potential of the coal basin until Brazilian miner Vale Limited started exploration work. The World Bank, which has received expressions of interest from Malawi and Mozambique to assist with geological mapping, hoped to identify copper prospectus in Zambia, Africa’s top producer of the metal. “There is a lot more copper in Zambia than what is known, so we hope to identify the areas with more prospect and then the government will be able to attract more investment to areas because

they know there will be a lot more certainty, a lot less risk,” he said. It is hoped that with the data availed it could also be used by respective governments when planning infrastructure development or water resource allocations.
The mapping fund hoped to unearth up to $1-trillion worth of new mineral resources on the continent, added De Sa.

Mixing liquid chemicals with hot metal to suppress dust and gas emissions Story of a great success of a unique approach exclusively engineered by Eltura/Misting SA in partnership with BHP Billiton.
I
Above: The fume capturing system which was installed
n the spirit of an objectives-based approach to improving the air quality within the Vaal Triangle Airshed Priority Area (VTAPA), just outside Johannesburg, BHP Billiton Metalloys committed to various Emission Reduction Strategy (ERS) Projects in order to reduce its particulate emission footprint within the Vaal Triangle. This commitment subscribed to their values of sustainability, prioritizing health and safety and being environmentally responsible, whilst supporting their communities. BHP Metalloys thus identified an ERS Project namely the capturing of fugitive emissions generated from the metal casting at the Oxygen Blown Convertor (OBC) located at West Plant in Meyerton. After considering various options it was decided to install a high pressure misting system with a specifically formulated, environmentally friendly, adhesive dust control agent (a derivative of our Micromass Particle product) that would not adversely affect employees' health whilst facilitating suppression of both fugitive dust as well as ambient dust. Due to its high risk, the project took more than two years from its conceptualization to its final delivery. A team of mechanical, chemical,
58 | July-September 2014
metallurgical and electrical engineers were involved along with chemists and technical experts. BHP Billiton and Eltura/Misting SA worked hand in hand to realise what has never done before: introducing water and chemicals within a casting environment. From a scientific perspective, “high pressure misting” requires an operating pressure of at least 70 bar: In order to ensure adequate gravitational settling of dust, atomised water mist is required in conjunction with a proprietary specifically formulated dust binding agent. At 70 bar (i.e. high pressure), a homogeneous (uniform) particle distribution of atomised water particles of approximately 10 microns in diameter are created. This is of high significance, owing to the fact that this coincides with the median particle distribution diameter for airborne dust (ambient, i.e., environmental dust) as well as fugitive dust. In accordance with the principles of colloid and interface science, in order to bind to and consequently gravitationally settle the dust, the atomised water particles should coincide with approximate diameter of the dust particles, which is thus only achieved at high pressures. Furthermore it is generally accepted that dust (which represents an aerosol suspension in air) is positively electrostatically charged. In order for the water droplets to efficiently bind to the dust a requirement therefore exists that the water droplets be coated with a negatively charged adhesive agent that is both oleophilic and hydrophilic, thus forming a “layer/shell” around the atomized water droplets. This would electrostatically neutralise the positively charged dust particles in order to facilitate the cohesion of the atomized droplets with the dust particles; thereafter, the newly formed larger particles containing the dust would collide with similar larger particles and merge to facilitate gravitational settling.
Lastly, the adhesive agent is essential to prevent redispersal of the dust – this is owed to cohesion of the settled dust to form a matrix. In conclusion the scientific principles involved in this approach represented a sound basis for dust suppression - both fugitive and ambient. This system consisted of eight (8) fans with spray manifolds to direct the fugitive emissions towards the south-eastern side vapour curtains. The dust was then entrapped within the fine mist, preventing the escape of fugitive emissions from the casting bay area. The reason this project was expedited was owed to the high impact emission reduction on the neighbouring communities of Meyerton Park and Sicelo. The expected emission reduction in fugitive emissions through the implementation of this project is expected to be approximately 10 tonnes per annum, and as such the project was well received as a great success within BHP Billiton as a world-first in treating emissions from casting areas. Thanks to this incredible journey, Eltura/Misting SA is now able to quickly and easily replicate what done at BHP Billiton in any casting environment. Compared to the only alternative option in these environments which is dust extraction (bag houses), our solution is way cheaper, easier to maintain, much lower in running costs and much faster to design and install.
