Large ore bodies of hematite are usually of sedimentary origin; also found in high-grade ore bodies in metamorphic rocks due to contact metasomatism, and occasionally as a sublimate on igneous extrusive rocks ("lavas") as a result of volcanic activity. It is also usually the cause of red soils all over the planet.

The key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state.. Magnetite and hematite are minerals of iron. Both have iron in different oxidation states, and they are in the forms of iron oxides.Another important difference between magnetite and hematite is that the magnetite is black …

Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...
