Magnetite is a common mineral and large deposits have been found in Sweden, Norway, the Urals, Italy, Switzerland, Australia, Brazil, United States (New Jersey, Arkansas, Utah, New York, New Mexico, California) and Canada (Ontario, Quebec, Nova Scotia). Magnetite is brittle and fractures unevenly.
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.
