Mining is the process of mining stuff out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron. Mining can also include other things like oil and natural gas.

Get PriceThe deep gold mine extends across an area of 4,268ha. It operates a gold mine accessed through two shaft systems, including the 2,995m deep Twin shaft complex and the South Shaft complex. The mine is further explored and categorised into four areas, namely Old Mine, Current Mine, Phase 1 .
Get PricePlacer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground.
Get PriceThe technical literature is replete with descriptions of and data on shaft sinking equipment, methods and costs. The subject of shaft sinking has been discussed at some length in an earlier Bureau of Mines bulletin. A number of shaft-sinking operations are described in detail in the series of information circulars on mining methods and costs, to some of which reference will be made later.
Get PriceMining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
