Iron oreWikipedia Iron ores are rocks and minerals from which metallic iron can be economically extracted Iron ore is the raw material used to make pig iron which is one of the main rawThe typical magnetite iron-ore concentrate has less than 1% phosphorus –7% silica and less than% aluminium See also Mineral processing
2018-6-28 The ore minerals in silicate iron ores are iron chlorites, usually accompanied by hydrous ferric oxides, and sometimes by siderite (25–40 percent iron). There is a negligible content of sulfur and up to 0.9–1.0 percent phosphorus. Silicate ores form beds and lenses in friable sedimentary rocks. They often have an oolitic texture. In the ...
2017-2-28 processed to make steel. High-grade iron ore mines can supply usable iron ore, known as direct-shipping ore, to blast furnaces, with minimal physical processing and no beneficiation. With direct-shipping ore, the reported production for crude ore and usable ore are the same. Ore from low-grade deposits must undergo beneficiation to increase the iron
2018-7-3 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. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
2007-8-31 By John D. Jorgenson. Domestic survey data and tables were prepared by Amy C. Tolcin, statistical assistant, and the world production table was prepared by Linder Roberts, international data coordinator. U.S. iron ore production rose by almost 3% in 2004 compared with that of 2003; consumption rose by 5%. World iron ore .
