Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

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.

The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can be inserted. The explosives are set off, and the iron ore is blasted out of the rock.
