Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, 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 …

The following mining techniques are standard for many minerals and elements; the type of deposit dictates which technique is employed: Open-Pit Mining: Ores closer to the surface are accessed by creating an open pit and then excavating the ore below for further processing.
