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.

More on Gold Prospecting Sulphides and Gold

Sulphide ores can contain gold in various forms, including those that are quot;free millingquot; and the harder to process refractory types of ores and ore bodies. As small scale or recreational gold miners we are most likely to spot and exploit quot;free millingquot; ores where the gold particles are visible to the naked eye or under slight magnification.
