Chemistry - Metallurgy Question with Solution | TestHub

Zinc blende contains ZnS which is first roasted partially and then subjected to reduction with carbon.

$\text{ZnS}+\frac{3}{2}{\text{O}}_2\stackrel{}{\to }\text{ZnO}+{\text{SO}}_2\left(\text{Roasting}\right)$
$\text{ZnO}+\text{C}\stackrel{\text{Δ}}{\to }\text{Zn}+\text{CO}\uparrow \left(\text{carbon}\text{reduction}\right)$
