Copper Mining and Extraction: Sulfide Ores
The 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 similar to the removal of impurities in the blast furnace.
