Iron ores are formed due to chemical reactions that combine iron and oxygen in marine and freshwater. The most important minerals in these deposits are iron oxides, magnetite (Fe3O4) and hematite (Fe2O3), goethite, limonite, and siderite. The ores containing large amounts of hematite or magnetite are natural or direct shipping ore.
