Iron ores are rocks and minrals from which metallic iron can be economically extracted. The ores are usually rich in iron oxide  and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of  magnetite (Fe3O4), hematite (Fe2O3),qoethite(FeO(OH)),limonite (FeO(OH).n(H2O)) or sidernite (FeCO3).

Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Most reserves of such ore have now been depleted. 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
