The chemical composition of slag formed during the smelting process in the extraction of copper is
The chemical composition of slag formed during the smelting process in the extraction of copper is
Updated On: Apr 15, 2024
- $Cu _{2} O + FeS$
- $FeSiO _{3}$
- $CuFeS _{2}$
- $Cu _{2} S + FeO$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
During smelting process of copper from copper pyrites reactions are
$Cu _{2} O + FeS \rightarrow Cu _{2} S + FeO$
$2 FeS +3 O _{2} \rightarrow 2 FeO +2 SO _{2}$
$Cu _{2} O + FeS \rightarrow Cu _{2} S + FeO$
$2 FeS +3 O _{2} \rightarrow 2 FeO +2 SO _{2}$
