copper mining and extraction sulfide ores

Copper Mining and Extraction Sulfide OresThe smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very simi
