Flotation of mixed oxide sulphide copper-cobalt minerals
Three cobalt-bearing oxide minerals are observed in the mixed ore, i.e. heterogenite, kolwezite and cupro-asbolane, while carrollite is the only cobalt-bearing sulphide mineral. A two-stage rougher-scavenger flotation process is used in which sulphides are extracted from the ore first.

Cobalt (Co) Ore | Properties, Minerals, Occurrence, Deposits
— After mining, cobalt ores are typically beneficiated through processes such as crushing, grinding, flotation, and/or magnetic separation to increase the cobalt concentration and remove impurities. Smelting and refining : Once the cobalt ore has been processed to a concentrated form, it is then smelted and refined to extract cobalt metal.

— From the above, it can be concluded that sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide as sulphidising agent exhibits a good selectivity of copper and cobalt flotation towards the gangue minerals. On the other hand, the use of ammonium sulphide induces higher metals recoveries with very low selectivity.
