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.

Magnetite (composition Fe3O4) has a specific gravity ranging from 5.0 to 5.1, and is sufficiently heavy to permit of its concentration from gangue by specific-gravity methods, which have …

The state's magnetite iron ore reserves total 16 billion tonnes, of which 6 billion tonnes are identified as economically demonstrated resources. Magnetite is enabling a steel technology transition in South Australia. Liberty Steel announced on 4 March it would phase out its existing blast furnace at Whyalla Steelworks and build a new DRI-EAF.

Iron ore pellets are made from both magnetite and hematite ores. Hematite ores are concentrated using a flotation process. Pellets include a mineral binder that represents about 2% by weight.

Magnetite: Magnetite is slightly harder with a hardness of about 5.5-6.5 on the Mohs scale. Specific Gravity: Hematite: Hematite has a specific gravity of around 5.3-5.4.
