Mining - Underground mining | Britannica.com

Mining - 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 ...

Iron ore – improving ore quality - AusIMM Bulletin

Many iron ore producers are facing challenging times due to price uncertainty and the need to process crude material with increasing levels of impurities. Upgrading the ore through beneficiation processes, particularly washing (scrubbing), to earn more per shipped tonne can be the key to improving ...

HPGR High Pressure Grinding Rolls

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

Mining | The Canadian Encyclopedia

May 22, 2019· They were fed by iron deposits at Trois-Rivières and operated from 1738 to 1883. Industrial demand for coal and iron spurred the expansion of mining and smelting in the late colonial period. Coal mining developed rapidly near Sydney, Cape Breton, and, in the mid-19 th century, major coal deposits were located on Vancouver Island.

Mineral processing - Wikipedia

This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores. At these mines a device ...
