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 (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry.
