Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known

The importance of iron ore to Western Australia’s economy

Mineral Resources and Ore ReservesEconomic ContributionProjects and DevelopmentsConclusionWA has enormous iron ore resources, currently estimated at 120 434 million tonnes (inclusive of reserves). Nearly two-thirds of these resources occur as goethite- and hematite-rich direct shipping ore (DSO) having inherently high iron content (>57 per cent Fe) that was naturally beneficiated by geological processes (particularly weathering) operating on and around specific iron-rich rock units. DSO is most abundant in particula在ausimmbulletin上查看更多信息

Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle.
