(B) FeO
(C) Al2O3
(D) ZnO
(E) NiO
Choose the correct answer from the options given below:
Solution
The compound(s) that are removed as a slag during the extraction of copper is :
<br/><br/>
$$
\mathrm{FeS} \stackrel{\mathrm{O}_2 / \mathrm{SiO}_2}{\longrightarrow} \underset{\text { slag }}{\mathrm{FeSiO}_3}+\mathrm{SO}_2
$$
<br/><br/>
$\therefore$ Only iron oxide (FeO) formed slag during extraction of copper.
