Q. The final step for the extraction of copper from copper pyrite in Bessemer converter involves the reaction
A) $Cu_{2}S + 2Cu_{2}O \rightarrow 6Cu + SO$
B) $4Cu_{2}O + FeS \rightarrow 8Cu + FeSO_{4}$
C) $2Cu_{2}O + FeS \rightarrow 4Cu + Fe + SO_{2}$
D) $Cu_{2}S + 2FeO \rightarrow 2Cu + 2FeCO + SO_{2}$
Explanation
(a)
In Bessemer converter, copper sulphide is partially oxidised to cuprous oxide which further reacts with remaining copper sulphide to form copper and sulphur dioxide.
$Cu_{2}S + 2Cu_{2}O \rightarrow 6Cu + SO_{2}$
