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 Mangnetie (Fe3O4, 72.4% Fe) hematite (Fe2O3 69.9%) goethite ((FeO(OH), 62.9% Fe) Limonite (FeO(OH) n(H2O) 55% Fe) siderite (FeCO3, 48.2%, Fe) Ores containing very high quantities of hematite or magnetite, typically greater than about 60% iron, are known as natural ore or direct shipping ore, and can be fed directly into iron-marking blast furnaces. Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel 98% of the mined iron ore is used to make steel. In 2011 the Finacial Times quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is " More integral to the global economy than any other commodity except perhaps oil".
