Geophysical methods in exploration and mineral environmental investigations by donald b.Hoover, douglas p.Klein, and david c.Campbell introduction in the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed.
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.
The first way in which proposed mining projects differ is the proposed method of moving or excavating the overburden.What follows are brief descriptions of the most common methods.220.127.116.11 open-pit mining open-pit mining is a type of strip mining in.
Near-surface valuable minerals and rocks from the earth.Surface mining is a largely practiced mining method throughout the world.In pakistan, numerous economically important minerals and rocks such as copper, gold, iron, limestone, dolomite, silica sand, aluminum etc, are being extracted through surface mining methods.
