Mining of Iron Ores - IspatGuru

14.03.2014  The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

Iron Ore Mining Techniques Metal Extraction

Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Iron Mining Process - Minnesota Iron

The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. Pellets The concentrate (the wet taconite powder) is rolled with clay inside large rotating cylinders. The cylinders cause the powder to roll into marble-sized balls. (This is like
