Not all copper deposits contain significant cobalt, but nearly all cobalt in the country is sourced from copper deposits. The DRC produces about 63% of the world's cobalt, with about 80% from industrial copper mines, and the remaining 20% gathered by artisanal mining .

Katanga produced 522,130 tonnes of copper and 101,000 tonnes of cobalt in 2012. [6] About half of the global proven cobalt reserves are in the Democratic Republic of the Congo (DRC), and over half of the cobalt extracted in 2017 came from the DRC. [7] Globally, most cobalt is used to manufacture lithium-ion batteries.
The residue is removed. A feed of matte and sulfide concentrate containing approximately 0.4% cobalt and 30% sulfur is pressure leached at elevated temperature and pressure in an ammoniacal solution to produce a solution of nickel, copper and cobalt. By boiling away the ammonia; copper is precipitated as a sulfide and sent to a smelter.
The project entails construction of a plant to process the copper and cobalt tailings in the Kingamyambo tailings dam and the Musunoi river tailings, which have an estimated total metal content of 1,676,000 tonnes of copper and 363,000 tonnes of cobalt. A Durban company, Metso ND Engineering, was selected to build the equipment. [3]
