52 E&MJ • JULY 2019 SUPPLIERS REPORT Weir Minerals Africa reported a Warman MCR 450 pump increased the throughput and reduced energy consumption in the secondary mill circuit at Anglo American Platinum's Mogalakwena mine. Weir originally proposed the pump solution, equipped with a rubber lining and metal impeller, because it offered a higher volumetric capacity. The larger impeller allows lower pump speeds. The rubber liner is lighter, and the hydraulic design has improved efficiency and wear characteristics, Weir reported. This al- lowed the mine to raise production from 600,000 to more than 700,000 dry met- ric tons (mt) per month. The pump was retrofitted to the exist- ing footprint. Once installed, it pumped 4,400 m 3 /month, which increased pro- duction to 760,000 dry mt/month. Online for 78.9% of the time, the pump was able to deliver significant sav- ings through lower power consumption, Weir reported. In response, the mine placed an order for three Warman MCR 450 pump conversion kits to retrofit the remaining Warman AH 20/18 RE pumps installed in the secondary mill circuit. The mine, near Mokopane in Limpopo province, is the world's largest open-pit platinum mine. Komatsu Acquires Immersive Through its subsidiary in Australia, Komat- su Ltd. agreed to acquire Immersive Corp. Pty. Ltd., which specializes in equipment simulators for training purposes. Komatsu reported the acquisition will enable it to meet its commitment to min- ing customers to offer training and work- force development solutions. "We look forward to working together with Immer- sive Technologies to enhance Komatsu's mining business and continue the suc- cess in its multiple-OEM simulator strat- egy," said Masayuki Moriyama, president, mining business division, Komatsu Ltd. Retaining its headquarters in Perth, Western Australia, Immersive Technolo- gies will operate under its existing name and branding as an independently man- aged subsidiary. Leadership at the compa- ny described the development as the start of the next phase of its evolution. "We now have the opportunity to contribute to the realization of Komatsu's strategy for mining, while also leveraging Komatsu's vast support network and advanced tech- nology portfolio," Peter Salfinger, CEO, Immersive Technologies, said. Separately, Komatsu announced the acquisition of Timberock International Ltd. Based in Elliot Lake, Ontario, Tim- berock supplies drilling and bolting tech- nologies and solutions. The acquisition enables Komatsu to offer a complete range of hard rock drilling feed and bolt- ing head products, and expanded capabil- ities in drifter repairs, Komatsu reported. AngloGold Re-contracts Veolia for Water Treatment AngloGold Ashanti contracted Veolia Gha- na Ltd. for water treatment at its Obuasi gold mine in Ghana. Under the three-year contract, the latter will operate and main- tain the four wastewater and two drinking water treatment plants at the mine site. Veolia completed a similar contract for the previous three years. Leadership at Veolia reported the new contract affirmed the company's opera- tional expertise in the field. "By optimiz- ing the process water treatment for the Obuasi gold mine, we have an opportunity to improve the productivity of this crucial operation," Christophe Maquet, director, Africa and the Middle East zone, Veolia Ghana Ltd., said. Epiroc Wins El Teniente's Order for Drills, Loaders Züblin International GmbH Chile Spa tapped Epiroc for multiple drill rigs and loaders that will be used to expand the El Teniente mine in Chile. The order in- cludes different models of the Boomer face drilling rig, Simba production drilling rig and Scooptram loader, as well as on- site technical support. The machines will be equipped with the Epiroc telematics system Certiq, allowing automated and intelligent monitoring of productivity and machine performance, Epiroc reported. Delivery, currently under way, will run through early 2020. Leadership at STRABAG Spa Chile described the Epiroc offer as comprehen - Pump Cuts Energy Costs, Raises Throughput Above, a Warman MCR 450 installed at Mogalakwena Mine.
