J & K CETJ & K CET 2012

Solution:

The first step of an extraction process is ore concentration which is done by magnetic separation and froth floatation in the extraction of copper from copper pyrites. Then the ore roasted in $O _{2}$.
$\underset{\text{copper pyrite}}{2 CuFeS _{2}}+ O _{2} \rightarrow Cu _{2} S +2 FeS + SO _{2}$
