The Karara mine located about 220km east of Geraldton in Western Australia holds 955 million tonnes of iron ore (36.4% Fe) and is the tenth biggest iron ore mine in the world. The mine was officially opened in April 2013 and is expected to produce more than 30 million tonnes per annum of magnetite concentrate for in excess of 30 years.

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.
