Hematite Fe2O3 - PubChem

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 world's iron and steel industries.
