The venture will reduce the partners’ reliance on third-party smelters to process their ore and make blister, a partially purified form of copper. According to Ivanhoe Mines, the 500 000 t/y direct-to-blister plant will be the largest copper smelter in Africa and one of the largest single-line smelters in the world, Ivanhoe said last week when announcing the award of the basic engineering contract to China Nerin Engineering Co.
Out of the investment, US $699M for construction, will come from the Kamoa-Kamula joint venture’s (JV) own cash flows, Zijin said in a filing. Known as Kamoa Copper, Ivanhoe and Zijin will own 39.6% each, the DRC government 20% and Crystal River Global Limited 0.8%. Construction of the plant is expected to take three years, Zijin added.
Copper concentrate output
Around 35% of current copper concentrate output from Kamoa-Kakula, which started producing in May, is treated at the nearby Lualaba smelter, majority-owned by China Nonferrous Mining Corp Ltd (CNMC), while the rest is transported to international smelters.
Kamoa-Kamula’s first phase is expected to produce around 200 000 t/y of copper, while Phase 2 expansion to 400 000 t/y is on track to be completed in the second quarter of 2022, Ivanhoe said last week.
The Canada-based company says Kamoa-Kakula has the potential to reach peak annual copper production of more than 800 000 t, which would make it the world’s second-largest copper mining complex, after the Escondida mine in Chile.
