 · An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.

 · 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.
