And iron in ...
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.
— Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin.Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite or kenomagnetite (Waychunas, 1991).Hematite is commonly thought to form from oxidation of magnetite in the near …
