Which one of the following reactions does not occur during extraction of copper ?

Answer:

Solution:

$C u F e S_{2} + O_{2} P a r t ia l ro a s t in g C u_{2} S + F e O + S O_{2} + F e S (v erys ma ll) + C u_{2} O (v ery s ma ll)$

$C u_{2} S + O_{2} \to C u_{2} O + S O_{2}$

$F e S + O_{2} \to F e O + S O_{2}$

$F e O + S i O_{2} \to F e S i O_{3}$

No formation of calcium silicate (CaSiO₃) in the extraction of Cu.
