Mining | Britannica, Mining: Mining, process of extracting useful minerals from the surface of the Earth, including the seas A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structureBulk ore sorting improves profitability and sustainability ,, These deposits require the mining, movement and processing of larger volumes of material per ton of valuable mineral The transportation, comminution and processing of these large volumes is expensive and energy intensive , This helps the mining operation to achieve the planned cut-off grade and optimize extraction of the resourceGold Production Line, Gold-bearing mineral have 98 species, 47 kinds of common, direct industrial value about 10 kinds,the form of generally divided into three categories, gold ore (Mountain gold mine, endogenous gold) and gold placer (alluvial, alluvial, beach type, slope deposits type and exogenous gold), and Associated gold (recovery from the non-ferrous minerals ):: WorstPollutedorg : Projects Reports, Context As mentioned in the 2008 Report, mine tailings are the waste materials after the minerals are separated from the ore in a mineral processing plantMine Planning, Summary The drive to exploit a mineral resource, such that it adds as much value as possible to the mining business, requires a continual update of the mine plan and the rapid implementation of any value-adding opportunities as they arise.
