Mining of Iron Ores – IspatGuru

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.

OpenPit. As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn''t require tunnelling into the earth and is a simple method of mining that yields high production rates.
