Mining

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 package 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

a The difference between surface and subsurface mining is that surface mining is on the Earth's surface and moves the unneeded materials out of the way in order to obtain the desired minerals and energy Subsurface mining doesn't remove the unneeded soils or rock out of the way instead it uses big machines to dig deep underground into deposits that hold the same minerals and energy there just
