Answer (1 of 2): Hematite ore is simply mined, crushed, and after that screened into either lump or fines. It is then immediately sold as such. The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite. But hematite ore usually contains larg...

Haematite is a slighty lower quantity of iron of about 60%-70% but the Magnetite ore is a finest high quality iron with 70% iron. Haematite is used as an important input in industrial iron ore and magnetite is mainly used in electrical industry . Haematite formula is Fe2O3 and Magnetite is Fe3O4.

1.Magnetite is black ore of iron and has more than 70% of iron whereas hematite is reddish ore and contains about 60% of iron. 2. Magnetite ore is found mostly in Tamil Nadu, and karnataka whereas hematite is found in odisha, jharkhand, madhya pradesh. 3. Magnetite is the best quality iron ore whereas hematite is inferior to magnetite.

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Magnetic hematite is not a true hematite in terms of its mineral content. Actually a man-made magnetic material, the content of magnetic hematite varies between manufacturers. The Mineralogy Database found that one sample was a "synthetic ceramic barium-strontium ferrite magnet." Companies that produce magnetic hematite keep their formulas a ...

Magnetite tends to be massive in shape, though you can find octahedral crystals of it occasionally. Hematite also can be massive, but will occasionally be tabular in shape. Hematite is the harder of the two minerals (6.5 vs. 5.5-6), but not by much.

Magnetite is an iron oxide with the chemical formula Fe 3 O 4 whereas hematite is an iron oxide with the chemical formula Fe 2 O 3. 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 …

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 from rock during concentration.
