Chibuluma Mine extracts its copper ore from its underground mine, then crushed, ground into powder and processed into concentrate. The company provides the copper mining and processing industry with high quality copper concentrates which can then be processed into refined copper.
First Quantum mines sulphide ore and oxide ore. Sulphide ore is treated via crushing, milling and flotation to produce copper in concentrate. The sulphide milling circuit maintains the production of finished copper as oxide ore is depleted and sulphide ore grades begin to fall as the mining horizon deepens.
The Malundwe and Chimiwungo deposits are mined sequentially by open-pit methods. Apart from copper, Lumwana Mining also produces cobalt, gold, and uranium. Lumwana ore, which is predominantly sulfide, is treated through a conventional sulfide flotation plant, producing copper concentrate for smelting.
