Flotation of mixed copper oxide and sulphide

For mixed oxide and sulphide ores, CPS is unsuitable for simultaneous flotation of copper oxide and sulphide minerals, as the sulphides are usually heavily depressed by the sulphide ions from NaHS additions necessary to sulphidise the oxide copper.

Flotation of mixed copper oxide and sulphide

The copper sulphide recovery did not decrease when processing the blended ore compared to treating the sulphide ore independently. At a blend of 70% sulphide ore and 30% oxide ore, the rougher scavenger copper recovery was as high as 95.5%. The copper recovery from the blended ore using a mixture of collectors was shown to be superior to the recovery obtained using only xanthate after ...

At the plant of the New Cornelia Copper Co., the oxidized minerals are dissolved from the ore with sulfuric acid in large vats, following crushing to about 3-mesh. The solution, containing copper, together with iron, alumina and the other impurities that dissolve from the ore, is passed th...

Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.
