Flotation of mixed copper oxide and sulphide minerals with ...
Kansanshi copper mine is situated in the north western province of Zambia. Weathering has given rise to a vertically zoned profile comprising leached, refractory, oxide, mixed and hypogene sulphide mineralisation. As a result of the mineral variations, the processing plant treats three distinct ore types; oxide, sulphide and mixed.

(PDF) A Review of the Flotation of Copper Minerals
Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2

Mixed Copper Oxide And Sulphide Minerals Processing
The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The method involves multistage addition of sodium sulphide (Na 2 S), sodium hydrogen sulphide (NaHS), or ammonium sulphide (NH 4) 2

improves the flotation response of the Kansanshi mixed copper ore. At a rougher copper concentrate grade of 8%, copper metal recoveries obtained with desliming were in excess of 70% compared to 58% achieved with base-line tests without desliming. It was further observed that desliming resulted in improved flotation rates for the sulfide minerals.

Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
