Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the worlds iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial

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. It can also be magnetized and was known has lodestone.
