Jan 04, 2016· Types of iron ore: Magnetite. With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore. That means it has to be concentrated before it can be used to produce steel. However, the ore’s magnetic properties help separate magnetite ore
Sep 16, 2020· Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
Hematite is harder than iron but also more brittle. It’s sometimes called a black diamond. If you would cut a Hematite in very thin plates, it would look transparent and red. Genuine Hematite does not have magnetic properties. The magnetism in the fake Hematine is because of the powdered iron oxide.

Jan 18, 2015· Hematite the mineral is essentially non-magnetic but often exhibits weak attraction to powerful rare-earth magnets or industrial-strength electromagnets. Anything more than that is usually due to the presence of magnetite as a secondary mineral, and that could well be unevenly distributed in hematite-rich iron ore deposits.
Jan 28, 2012· Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite; therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite.
