oxide ore cobalt

Cobalt extraction - Wikipedia

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 in the circuit.
