Processing copper sulphide ores RICHMOND

A number of alternative process routes exist for the treatment of copper ores, particularly ores in which the copper is present as copper sulphides such as chalcocite Cu 2 S, covellite CuS, bornite Cu 5 FeS 4 and enargite Cu 3 AsS 4. These routes include in-situ leaching, heap leaching and agitated tank leaching.

Sulfide Ore an overview ScienceDirect Topics

A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.
