Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight.

the chemical composition of direct-ship and beneficiated iron ores can be divided into high-grade hematite ores, with 62–65% fe and low sio 2 and al 2 o 3, largely from brazil and south africa; a number of australian, indian, and other iron ores with ∼60–62% fe; 56.5–61.0% fe high-loi martite–goethite australian ores; and high-loi australian cid …
In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others.
The iron and steel sector directly accounts for 2.6 gigatonnes of carbon dioxide (Gt CO 2) emissions annually, 7% of the global total from the energy system and more than the emissions from all road freight. 1 The steel sector is currently the largest industrial consumer of coal, which provides around 75% of its energy demand.
