Understanding Iron Ores and Mining of Iron Ore IspatGuru

Apr 03, 2015 Typically, a deposit must contain at least 25 % Fe to be considered economically recoverable. Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v)

Iron ore extraction techniques ScienceDirect

Jan 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 ).
