what is the basin of iron ore

  • Iron ore - Wikipedia

    Iron 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). Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The Mineral deposit - Iron Ore, Ore Bodies, Mining BritannicaWhat is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals Iron Ore: Sedimentary Rock - Pictures, Definition
