OverviewSourcesMine tailingsExtractionProduction and consumptionAbundance by countrySmeltingSee alsoIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
Iron ore mining and dressing tec-science
IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingIron does not occur in nature as a pure substance but as a compound in rocks, which can contain up to 50 % iron. These ferrous rocks are also called iron ores. The iron compounds contained therein are mainly iron oxides, but also iron carbonates or iron sulphides. The most important iron oxides include: 1. magnetite: Fe3O4 2. hematite (haematite):Iron Ore: From Mining to Processing to Dust Control

Iron Ore Statistics and Information U.S. Geological Survey
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.
