sulphidation of copper oxide ores for flotation

Copper Oxide Ore | Scientific.Net

Abstract: The copper oxide ore in Dali, which contains 0.69% of copper and 11.24g/t of silver, was beneficiated by sulphidizing - xanthate flotation method. The flotation tests were carried out systematically with sodium sulfide as sulphidizing agent and butyl xanthate + ammonium dibutyl dithiophosphate as the combined collectors.

Sulphidizing reactions in the flotation of oxidized copper ...

The rate and extent of the heterogeneous reaction that takes place between dissolved sodium sulphide and synthetic tenorite is studied for a wide range of sodium sulphide to copper oxide ratios. Besides the sulphidization with the formation of a copper-sulphide layer, a substantial oxidation of sulphide ions takes place at the surface of the solid.
