(iii) Cu2S (copper sulphide) Explaination Copper is usually extracted from its sulphide oxide ores. Cu2O (copper oxide) is reduced to Cu (copper) by its reaction with Cu2S (copper sulphide). 2Cu2O + Cu2S --> 6Cu + SO2. SO2 gas is formed during this reaction have to be safely removed from the reactor. Hope this helps you.

Innovations: Introduction to Copper: Mining Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores. specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
