Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
