Improving the efficiency of oxide copper–cobalt ores …
From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non-selective sulphidiser. Best results were recorded with a synergistic combination of sulphidisers; a 1/1 mixture of sodium hydrosulphide and ammonium sulphide.
flotation of cobalt copper silver minerals
Flotation Mineral Processing. Flotation is an economical and effective separation of refined gold technology, especially for these ores that are not suitable for other processes, such as gold bearing copper ore, base metal ore, copper nickel ore, platinum group ore, etc. Flotation is also used to remove impurities before hydrometallurgical treatment ie, carbon pre flotation.

Cobalt Flotation Recovery
Hydrometallurgical schemes have utilized a ferric chloride solvent in an oxidative leach to treat the copper concentrate and leave the cobalt in a cobalt-enriched residue. Although successful, this scheme has the disadvantage of disrupting the production of a salable copper product and would involve a major capital investment in a leach and electrowinning plant to …
