Mining

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 largest part of the volume of these minerals extracted worldwide is a byproduct of copper extraction (rhenium 90%, cobalt 70%, molybdenum 60%) (Copper Alliance, 2015). The market prices of byproduct minerals will mainly be determined by the tradeoff between the volume of byproduct generated and the market demand for this byproduct.

Mining industry of Nigeria

Mining is the extraction[removal]of minerals and metals from the earth. The Nigerian Coal Corporation (NCC) is a parastatal corporation that was formed in 1950 and held a monopoly on the mining, processing, and sales of coal, lignite, and coke products until 1999.. Coal was first discovered in Enugu in 1909 at the Udi Ridge in Enugu,This was found by a British mine Engineer known as Albert Kitson.

Trace Minerals What They Are and Why the Body Needs Them

Aug 16, 20170183;32;Much like how elemental minerals buttress rocks and other solid structures, trace minerals serve as reinforcement for bones, cartilage, and other bodily tissue. While they might appear solid and unchanging, your bodys bone structure is in a constant of repair and renewal. Trace minerals function as the lattice architecture.

The Problems

Though solid tailings present environmental issues, the primary problem comes from wet tailings. Wet tailings are left to sit in dams which are susceptible to rupture; if that happens, the tailings are released uncontrolled into the environment. The problems surrounding the use of strategic elements go largely unnoticed by the public.

Mining valuable minerals from seawater a critical review
