Magnetite vs. Hematite — What's the Difference?
Magnetite, with the chemical formula Fe3O4, is one of the primary iron ores and is known for its strong magnetism. Hematite, on the other hand, has the formula Fe2O3 and is also a significant source of iron but lacks natural magnetism. Both are iron oxides, but they differ in their chemical composition, which results in different properties.
Hematite
The mineral form of iron (III) oxide, having the chemical formula as Fe 2 O 3 is called hematite. It is usually present in areas having mineral hot springs or still standing water. Iron from the mineral gets precipitated out of water and collects in the form of layers at the bottom of springs, lakes or other standing water bodies.
