The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
mining and ore processing . waste rock and tailings from mercury mining, and other extraction processes where mercury is uncovered, can still contain small or large amounts of the toxic substance. mercury that is not processed or claimed during mining and ore processing can make its way into the environment if the mining waste is not stored price
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Some sulfides (pyrite, chalcopyrite, galena and antimonite) are also enriched with silver particles. The silver content of galena is as high as %, sometimes %. The grinding process can not dissociate such fine silver particles. 2. Extraction Method of Silver in GoldSilver Ore #1 Gravity Separation Method
The size of the ore bed increases as mining continues, and eventually, the pit becomes a very large bowlshaped hole in the earth''s surface. When the ore is found in a wide area but it''s not very
Mining of iron ore is a highly capital and energyintensive process. Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal
