How is copper extracted from its Sulphide ore ? Explain ...

This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. (Cu^{2}S + O^{2} → 2Cu + SO^{2}) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper; 98 – 99.5 % pure.

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More 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.
