Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody , lode , vein , seam , reef or placer deposits which forms the mineralized package of economic interest to the miner.
Ores recovered by mining include metals , coal , oil shale , gemstones , limestone , dimension stone , rock salt , potash , gravel , and clay . Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water .
Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
