  • in extract of copper

    In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.
