Copper Mining and Extraction Sulfide Ores

Some impurities form a slag such as FeO.SiO 2 , which floats on the surface of the liquid like oil on water and is easily removed. Courtesy of Xstrata. The smelter for sulfide produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching from oxide ores.
