Nov 09, 2021 Hematite is an iron ore that contains iron in the form of Fe 2 O 3. It is a significant source of iron extraction. Hematite is a mineral that is paramagnetic. As a result, it can be drawn to an external magnetic field. Hematite is abundant in rocks and soil. Hematite’s magnetic properties are caused by unpaired electrons.

It has been found that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is very insignificant.

Magnetite has higher iron content than hematite. But hematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentrated before it can be used to produce steel.
