The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe), or siderite (FeCO3, 48.2% Fe). 2015年1月1日  The three most common iron ore minerals are magnetite, hematite (the spelling “hematite” is preferred here over “haematite”), and goethite, which together Mineralogical, chemical, and physical characteristics of iron ore2015年5月1日  Introduction.
