Iron ore: Confounding the expectations of experts | Edison
We predominantly mine two types of rock for iron ore: haematite (iron III oxide) and magnetite (iron II, III oxide). In general, both are found as sedimentary deposits in rocks that are at least 1.8bn years old and thought to be the product of iron-rich waters at a time when oxygen was rare in oceans and rivers.

Magnetite forming in iron pipes - MERUSONLINE
Magnetite forming in iron pipes. Magnetite, with chemical formula: Fe3O4, is an iron ore found in igneous, metamorphic rocks. It belongs in the same group of iron ore as the hematite or the maghemite. Magnetite is a chemical compound of iron and oxygen and therefore an oxide. Magnetite is physically rather stable, as it is an octahedral crystal.
