Flotation of mixed copper oxide and sulphide minerals with

Mar 01, 2009· Generally copper oxide minerals do not respond well to traditional sulphide copper collectors and require alternative flotation techniques to concentrate the copper oxides. The classical method involves controlled potential sulphidisation (CPS) to sulphidise the surface of the oxide minerals by the addition of a sulphidisation agent, such as sodium hydrogen sulphide (NaHS).

Improving the efficiency of oxide copper–cobalt ores

Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. 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.

Tetrazinan-thione collectors for copper oxide mineral

Oct 15, 2019· Copper oxide minerals show the favorable hydrophilicity due to their surface hydration in aqueous solutions, to promote their hydrophobicity through surfactant/collector attachment is of vital importance in their flotation beneficiation. The oxide copper minerals collectors include oxime surfactants [,,,,, ], fatty acids, phosphates/phosphonates [17,18], and sulfydryl chelators [,,,,, ].

Flotation of Copper oxide ore Fodamon Machinery

For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is easy to float, and copper oxide can not be recovered by a single flotation method. Copper oxide minerals in a separate state are called free
