Longwall mining is one method of pillar extraction, now the most common method in use in Australia, and probably worldwide. Before longwall mining methods had been developed to operate satisfactorily in most conditions, a lot of pillar extraction was carried out using continuous miners, and such methods are still in use in places for a variety

Environmental Risks of Mining

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Extraction Of Copper Mining, Concentration, Smelting

Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore

Extraction of Resources  Geology

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
