In the extraction of copper from its sulphide ore, the metal
Copper (I) sulphide ( C u 2 S). 55%. Solution: 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 → 6 C u + S O 2 ↑. Here C u 2 S behaves as reducing agent.
