Iron ore Wikipedia
Iron ores are rocks and minerals from which metallic iron can be economically extracted The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red The iron is usually found in the form of magnetite (Fe 3O 4, 724% Fe), hematite (Fe 2O 3, 699% Fe), goethite (FeO(OH), 629% Fe), limonite (FeO(OH)n(H2O), 55% Fe) or siderite (FeCO3, 482% Fe)
