Copper Mining and Extraction Sulfide Ores

The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to
