Mining is the extraction of valuable minerals or other geological materials from the Earth usually from an ore body lode vein seam reef or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals coal oil shale gemstones limestone chalk dimension stone rock salt potash gravel and clay.

Coal mining processing plant in Nigeria. This coal mining project is an open pit mine located in Nigeria announced by mining company - Western Goldfields - that it has discovered 62400000 tonnes of proven reserves of coal deposits worth US1.2 billion which could be used
Mining remains an essential and growing part of the modern industry. By some estimates it makes up nearly 45 of the total global economy and mineral production continues to increase as demand for raw materials grows around the world.. However many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
The platinum-group metals abbreviated as the PGMs alternatively the platinoids platinides platidises platinum group platinum metals platinum family or platinum-group elements PGEs are six noble precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block groups 8 9 and 10 periods 5 and 6.
Industrial minerals are extracted primarily by surface mining which is less expensive than underground mining. However even when a location is determined to have a potentially economically viable mineral deposit the costs of drilling extraction and transporting the raw materials still must be considered and weighed against the current .
