  • 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. It is therefore essential for the

    Hematite Mineral Description. Hematite is an iron-oxide mineral of the Oxides and Hydroxides group, with structural formula [alpha-Fe 2 O 3].The structure is similar to that of corundum, and consists essentially of a dense arrangement of Fe 3+ ions in octahedral coordination with oxygen atoms in hexagonal closest-packing. The structure can also be described as the stacking of sheets of
