To expose the coal layer, the layers above it need to be removed. The vegetation and soil, called the topsoil, is removed and kept aside so that it can be re-deposited in the area after mining. If there is a layer of rock above the coal face, called the overburden, this is also removed before the coal can be excavated.

Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
