Text Solution

Verified by Experts

The correct Answer is:
A
Explanation. Blistered Cu is formed due to escape of ` SO _ 2 ` during solidification. Blast furnace is used in the metallurgy or iron. In reverberatory furnace, basic impurity (FeO) combines with acidic flux to form ` FeSiO_3 ` slag. Hall - Heroult process is used for extraction of Al.
