Copper Mining and Extraction: Sulfide Ores (11-14)

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.

Understanding Copper Oxides & Sulfides

Copper mineralization for deposits starts as primary sulfide mineralization. Over time, exposure to surface water and air turns some of these minerals into oxides. Oxides can often be dissolved in weak acid, making copper recovery efficient. Sulfides, on the other hand, don't leach, so they require a different process.
