Chemicals Used in Mining Hesperian Health Guides
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

Where mineralized rocks become outcropped or shattered, the sulfide minerals undergo chemical changes due to air, groundwater and heat, giving rise to the other main variety of copper minerals the oxidized ores. There is no shortage of copper resources. In fact, copper is one of the most abundant of the metallic elements in the earth''s crust.
It is a solid mixture of oxides, sulphides and sulphates. One reaction that takes place is: 2CuFeS 2 (s) + 3O 2 (g) 2FeO (s) + 2CuS (s) + 2SO 2 (g) As SO 2 is hazardous, it has to be removed from the gases released into the environment. One way of solving the problem is to convert it to sulphuric acid.
