It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe. It has been the dominant iron ore mined in Australia since the early 1960s. Approximately 96% of Australia's iron ore exports are high-grade hematite, most of which has been mined from deposits in the Hamersley province of Western Australia (WA). The Brockman Iron Formation in the Hamersley province is the most significant host for high-grade hematite iron ore deposit.

Steel is one of the main items on a list of things made of iron.Steel is made of approximately 98 percent iron, according to Minerals Education Coalition. Things made of steel include things like vehicles, surgical tools, home appliances, nails, cans, steel beams

Magnetite contains 72.4% iron, which is higher than hematite, but the presence of impurities usually results in magnetite ores having lower ore grade (generally 20-30% Fe) than hematite ores, making it more costly to produce concentrate for steel smelters. Magnetite mining is an emerging industry in Australia with large deposits, including Balmoral's George Palmer deposit, being developed in the Pilbara region of WA.

While iron ore deposits were known, like the [Mount Whaleback mine|Mount Whaleback deposit] discovered in 1957 by Stan Hilditch, it was not until 1960, when theAustralian Government lifted the embargo on iron ore exports it had put in place because of concerns the mineral was in short supply, that mining began in earnest. Up until the mid-1960s, iron ore production in Western Australia, and Australia as a whole, was negligible, in the range of less than 10 million tons a year. By the mid-1970s, this figure had reached 100 million tonnes, with the majority coming from Western Australia. Production slightly declined in the 1980s but it improved in the 1990s, reaching 150 million tonnes for the country by 1997 and 200 million tonnes by 2003.
The first mine in the Pilbara, the Goldsworthy mine, was developed by Utah Development Co. in 1965. A private railway line, the Goldsworthy railway, as well as port facilities at Finucane Island, Port Hedland, were also constructed. On 1 June 1966, the first shipment of iron ore from the Pilbara left on board the Harvey S. Mudd.
BHP's operations in Newman date back to 1968, when the Mount Whaleback mine was opened, the biggest single-pit Open-pit iron ore mine in the world. A new town, Newman, was constructed, as well as a 426 kilometre railway line, the Mount Newman railway.

Once blended, iron ore is smelted and alloyed with metals (nickel, chromium, manganese, vanadium, molybdenum or titanium), which can then go on to produce different types of steel. 
The majority of iron ore produced in Australia is direct shipping quality hematite ore. However, operations that extract magnetite and other types of ore requiring beneficiation are attracting increasing interest.]]> 2017-06-14 05:42:34 UTC https://padlet.com/laura_berry2/hle64qmkbqsl/wish/176352775 process abi_anthony https://padlet.com/laura_berry2/hle64qmkbqsl/wish/176353226 The extraction of iron ore is generally performed through a blasting and removal process from large open pit mines, before it is crushed, screened and blended for export or local consumption.

• Magnetite has the chemical formula of FeO·Fe2O3 or Fe3O4. Chemical formula of hematite is Fe2O3.
• Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state.
• Magnetite has higher iron content than hematite; therefore, its quality is higher.
• Magnetite is black in colour, but hematite has a variety of colours.
• Hematite is a component of rust but magnetite is not.
• Magnetite is a naturally strong magnet, but in hematite magnetism occurs upon heating.
• Magnetite has a black streak, whereas hematite has a reddish brown streak.
• Hematite has a rhombododecahedral crystal structure. Magnetite commonly shows octrahedral crystal structure.
