China-based Zijin Mining’s board has approved an investment to support the construction of a 500ktpa smelter for Kamoa-Kakula copper project in Democratic Republic of the Congo. The total investment for the project is estimated at around USD 769 million, including USD 699 million for construction of new smelter. With a construction period of three years, the project will be funded through Kamoa-Kakula Copper’s own cash flow.China Nerin Engineering has secured a basic engineering contract for the direct-to-blister flash smelter at the Kamoa-Kakula copper complex. Designed to be built adjacent to the phase I and phase II concentrator plants, the new smelter will feature an advanced technology supplied by Finnish company Metso Outotec. The new smelter will be used for the processing of copper concentrate produced by Kamoa-Kakula’s phase I, phase II and phase III concentrators. Claimed to be one of the largest and single-line blister-copper flash smelters across the world, the new smelter is designed to produce blister copper per annum.Zijin Mining and Ivanhoe Mines each own 39.6% stake in Kamoa-Kakula project, while the DRC government owns 20% stake and Crystal River Global has 0.8% stake in the project.
