Australia has always traditionally had large reserves of hematite, and since the 1960's it has been the main iron-bearing mineral mined in ore. Around 96% of all iron ore exported from Australia is hematite of high grade. The Hamersley province in Western Australia is the source of the majority of the hematite mined in Australia, around 80%.

Limonite is a general term for a mixture of fine-grained iron oxides, generally dominated by goethite, but also possibly containing hematite, lepidochrocite and other minerals. It forms from the weathering of other iron minerals, and may be precipitated by iron rich surface or ground water. It is a useful field term, and has been frequently used in the literature.
