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.
Tungsten is mostly obtained from the minerals scheelite and wolframite. Tungsten is not refined by smelting or through any other method through which other metals are refined since it has the highest melting point above any other metal. The surface mining methods are used when the tungsten minerals are found in the earth's surface where underground digging is not required.
The U.S. mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks.
