Cobalt extraction - Wikipedia

Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematite.The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte.Oxide concentrates are introduced at this leaching step to maintain the acid balance ...

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate containing 27 to 36% copper. In the smelting operation ...

What is Cobalt? - Mining Information

27/10/2018  Mining. Most cobalt is acquired as a by-product of nickel refining, as well as the mining and smelting of copper. Cobalt can also be obtained from the main cobalt ores of cobaltite, glaucodot, erythrite, and skutterudite. The supply of cobalt greatly depends up the supply and demand of both nickel and copper due to it generally being produced as a by-product. Methods to extract from copper and ...
