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.

Hematite bonds are common and strong, but they are not stable during reduction. But when hematite bonds are reduced to magnetite, silicate bonds remain unaltered. They soften and melt later (Niiniskorpi, 2004). Acid pellets showed high reduction degradation due to the presence of more hematite bonds and less silicate bonds.
