“Mining Magnetite for your future.”

Magnetite reacts with oxygen to produce hematite. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks. Magnetite also occurs in many sedimentary rocks, including banded iron formations. In many igneous rocks, magnetite-rich and ilmenite-rich grains occur that precipitated together from magma.

A Description of Magnetite - Rocks And Minerals 4 U

Magnetite. Magnetite is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4, commonly called ferrous-ferric oxide, and is valuable as an iron ore. Magnetite reacts with oxygen to produce hematite, another iron ore. In crystalline form magnetite is usually octahedral.

Hematite - an overview ScienceDirect Topics

Hematite is the stable end product of oxidation of magnetite or the inversion of maghemite. It can also form during oxyexsolution of titanomagnetite during slow cooling or by inversion of titanomaghemite during heating. Weathering and dehydration reactions of iron oxyhydroxides, such as goethite and ferrihydrite, will also produce hematite.
