For the extraction of iron, haematite ore (Fe2 O3) is used.
Hematite is a common iron oxide with the formula Fe2 O3 and is widespread in rocks and soils.
Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C. Huge deposits of hematite are found in banded iron formations.
Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron (II) oxide and (FeO), which is rare and iron (II, III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite.
As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is readily attacked by acids. Iron (III) oxide is often called rust because rust shares several properties and has a similar composition.
