Open-pit mining Wikipedia

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocksMining of Iron Ores IspatGuru,Mar 14, 2014· Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores.Iron Bridge Magnetite Project Mining-Technology,Dec 30, 2020· The total mineral resources of the iron ore mine are estimated to be 5,448Mt graded at 30.4% of Fe.
