lution concerns in the mining industry. Removal of overburden to access the ore can pose major problems in storage and reclamation. The overburden (wastetoore) ratio for surface mining of metal ores generally ranges from 2:1 to 8:1, depending on local conditions. The ratio for solid wastes from underground mining is typically 0.2:1.

Mining Metals. 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 be separated.

Overview of the different methods of extraction of metals. Metals are found in the Earth either as compounds or, in the case of very unreactive metals, as the crust of the uncombined element. The rock that contains the metal is called an ore. Common metal ores include bauxite (aluminium oxide), haematite (iron oxide), zinc blende (zinc sulphide), galena (lead sulphide), and cinnabar (mercury sulphide).
