Question

In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to

C u_{2} O

which reacts with the remaining

C u_{2} S

(sulphide ore) to give copper metal.

C u_{2} S + 2 C u_{2} O \to 6 C u + S O_{2} ↑

Here

C u_{2} S

behaves as reducing agent.
