Copper Sulfide - an overview ScienceDirect Topics

All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate, rather than the elemental

Flotation of Artificial Sulfide Minerals

2019-10-20  Flotation of Artificial Sulphide Minerals. Flotation was carried out with purified potassium amyl xanthate at a pH of 10.5. C.P. grade NaOH was used as the pH regulator. Flotation time was 5 minutes. It is evident that the recovery of copper increases with an increase in the time of sulphidization of the chrysocolla.
