Question

The first step in the extraction of Cu from copper pyrites is (A) reduction by carbon (B) electrolysis of ore (C) roasting of ore in O 2 (D) magnetic separation

Tardigrade Admin · Accepted Answer

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}

.

copper pyrite 2 C u F e S_{2} + O_{2} \to C u_{2} S + 2 F e S + S O_{2}

Q. The first step in the extraction of $C u$ from copper pyrites is

reduction by carbon

electrolysis of ore

roasting of ore in $O_{2}$

magnetic separation
