Question
In the extraction of copper from its sulphide ore, the metal is finally obtained by thee reduction of cuprous oxide with
Options
A.copper (I) suphide (Cu2 S)
B.sulphur dioxide (SO2)
C.iron suphide (FeS)
D.carbon monoxide (CO)
Solution
In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu2O which reacts with the remaining Cu2S (sulphide ore) to give copper metal.
Cu2S + 2Cu2O → 6Cu + SO2 ↑
In this process Cu2S behaves as reducing agent.
Cu2S + 2Cu2O → 6Cu + SO2 ↑
In this process Cu2S behaves as reducing agent.
