Flotation of mixed copper oxide and sulphide minerals

2009-3-1  The total and acid soluble copper assays of the tail from Test D were 0.19% and 0.16% Cu, respectively. This shows that the residual copper found in the tail was mainly associated with copper oxide minerals. The total copper, sulphide copper and oxide copper recoveries of 95.5%, 98.2% and 89.4%, respectively.

Flotation of mixed copper oxide and sulphide minerals

The copper sulphides present in the blend were bornite and chalcopyrite, while the oxides were malachite and minor azurite. From previous flotation investigations of mixed copper oxide and sulphide minerals using xanthate and hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sulphide recovery as ...
