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 ...

Flotation of mixed copper oxide and sulphide minerals

Abstract Sherwood Copper’s Minto Mine processes a high grade copper–gold deposit in Yukon, Canada. The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with ...

Mixed copper sulfide and oxide - Froth Flotation (Sulphide ...

2021-8-15  You float sulphides with PAX and them add your Hydroxamate to get oxides (add NaHS if your material responds to the sulfidiser). In a traditional way, sulphide and oxide copper minerals do not recover at the same rate. You typically handle their flotation in a sequential manner: sulphide species #1 followed by oxide minerals.

These ions react with the copper oxide minerals to form a sulphide layer on the surface of the oxide minerals (Zhou Chander, 1992).The sulphidiser concentration can be controlled by measuring the E S potential of the pulp using a sulphide ion-selective electrode. The reaction between
