Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron-derived oxide and vary in color from bright yellow, Dark grey, Deep purple, To rusty red. The iron itself is usually present offered in the shape of of magnetite fe3o4, Hematite fe2o3, Goethite feo oh, Limonite feo oh . N h2o or siderite 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 have the potential to be fed directly into iron, Making blast furnaces. Most reserves of such ore have now been depleted. The essential base material for iron is iron ore material used to produce functioning as, Pig iron among the top Fundamental materials to make steel. 98% of the mined utilization derived from iron-bearing ore occurs in it has, Make steel. Indeed served as argued that iron-rich mineral deposits are known as more integral to the global economy beyond all other options commodity, Except perhaps oil
