General Principles and processes of Isolation of Elements
normal
Formation of metallic copper from the sulphide ore in the normal thermo-metallurgical process essentially involves which one of the following reaction :
A
$CuS + \frac {3}{2} O_2 \rightarrow CuO + SO_2;$
$CuO + C \rightarrow Cu + CO$
B
$CuS + \frac {3}{2} O_2 \rightarrow CuO + SO_2;$
$2CuO + CuS \rightarrow 3Cu + 2SO_2$
C
$CuS + 2O_2 \rightarrow CuSO_4;$
$CuSO_4 + CuS \rightarrow 2Cu + 2SO_2$
D
$CuS + 2 O_2 \rightarrow CuO + SO_2\,;$
$CuO + CO \rightarrow Cu + CO_2$
