Mineral Extraction The Environmental Literacy Council

Extracting minerals either from or below the surface of the Earth requires the movement of a lot of soil. Large areas of land, as well as the surrounding ecosystem, are affected; if the overburden is not properly cared for, it can cause further damage to the environment—including the filling in of wetlands or disturbing other watershed areas.

Extraction of Resources Geology

Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, 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
