Iron | Geoscience Australia
Mining. Most iron ores mined today comprise the iron oxide minerals hematite, Fe 2 O 3 (70% Fe); goethite, Fe 2 O 3 s H 2 O, (63% Fe); limonite, a mixture of hydrated iron oxides (up to 60% Fe); and magnetite, Fe 3 O 4 (72% Fe). As with most iron ore mines throughout the world, all the major Australian iron ore mines are open cut.
Iron Ore Processing, General
Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.
