Hematite ore has been the primary type of ore mined in Australia since the early 1960s, according to Geoscience Australia. Approximately 96 percent of the continent's iron ore exports are high-grade hematite, and the majority of its reserves are located in the Hamersley province of Western Australia.

At present, the bulk of our iron ore exports would simply not be compatible, as there are too many impurities. Australia exports two main types of iron ore: hematite and magnetite. Hematite is mined in Western Australia's Pilbara. It's a naturally higher-grade ore (56–62 per cent iron) and makes up almost all (96 per cent) of our exports.

Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.
