Iron ore WikipediaUSGS Minerals Information Iron Ore
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 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 industri
