Mining Wikipedia

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.

10 Different Types of Mining Operations and Mines

There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.
