Iron ore - Wikipedia

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".Mineral Properties, Photos, Uses and Descriptions,Minerals are materials that meet five requirements. They are: 1) naturally occurring, 2) inorganic, 3) solids, 4) with a definite chemical composition, and, 5) an ordered internal structure.,Hematite - the most important source of iron ore and mineral pigment since prehistory. Mineraloids. Mineraloids are amorphous naturally-occurring,USGS Minerals Information: Iron Ore,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.
