iron ore formula

iron ore formula,Iron ore - WikipediaIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite.iron ore formula,Iron Ore: Sedimentary Rock - Pictures, Definition & MoreIron ore is a chemical sedimentary rock that people have used as an important source of metal.
