Copper-cobalt ores typically contain cobalt ranging from 0.01 to 0.8 %, and their coexistence with copper results in a complex mineral composition [6].After flotation, it is feasible to separate the ore into copper-cobalt oxide and sulfide concentrates [7].The oxide concentrates primarily contain copper and cobalt in the forms of malachite, azurite, and heterogenite [8], [9].
