Answer :- Copper (1) sulphide (CuS) .......In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu,0
‘which reacts with the remaining Cu,S (sulphide ore) to give copper metal.
CUS +2Cu0 — 6Cu +S0, 1
In this process, Cu,S behaves as reducing agent.
