Mining of Iron Ores IspatGuru

The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

Iron ore extraction techniques ScienceDirect

01-01-2015· DSOs, when mined, typically have iron (Fe) content of between 56% and 64% Fe. By comparison, magnetite ore typically has a much lower iron content of between 25% and 40% Fe and in this form is unsuitable for steel making. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3 O 4 ).
