cobalt ore recovery

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 calcine is subsequently leached with sulfuric acid from the spent copper recovery concentrates are introduced at this leaching step to maintain the acid balance in the circuit
