A Review of the Flotation of Copper Minerals | O.

Copper is most commonly present in the earths crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). Copper also occurs to a lesser extent in oxidised minerals, for instance, malachite (Cu 2 (OH)CO 3 ), azurite (Cu 3 (OH) 2 (CO 3 ) 2 ) andflotation in mining copper and gold oxide ore,Feb 05, 2018· treats a mixed oxide/sulphide copper-gold vein deposit with very copper-gold ores with a high gangue acid The Kansanshi Mine (First Quantum Minerals Ltd) treats a mixed copper flotation, mixed sulphide/oxide ore, controlled potential.AN INVESTIGATION OF COPPER RECOVERY FROM,Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged.
