Concentration Of Copper Oxide Ores

Concentration of ores

The preliminary step in metallurgical process is removal of these impurities. This removal process is known as concentration of ore. It increases the concentration of the metal of ...

Copper Ore

Generally such oxide copper-cobalt ores are recovered by sulphidisation process. In Congo, the copper mineralisation is mainly composed of malachite, pseudo malachite, and chrysocolla. Cobalt in such oxide copper ores occur as heterogenite. Since the copper minerals are oxide in nature, they do not respond to flotation with xanthate collectors.
