Copper Mining and Extraction: Sulfide Ores

b) Formation of blister copper by reduction of copper sulfide: Cu2 S(l) + O 2(g) → 2Cu (l) + SO 2(g) from air blister copper Stage 6: Anode casting The blister copper produced by this process is 99% pure copper. The name ‘blister’ copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of
