The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.
Our global network is strategically located near key Atlantic and Pacific markets. It includes the Huntly mine in Australia, the second largest bauxite mine in the world. Alcoa offers bauxite from its mines to meet customer-specific needs and provide a consistent, reliable, and sustainable supply of raw material for refineries around the globe.
Aluminium is the third most abundant element in the Earth's crust, but does not occur as a metal naturally. The first step in producing aluminium is mining its ore – bauxite.Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe.
Topsoil from the mining site is stored so it can be replaced during the rehabilitation process. Reserves will last for centuries Although demand for aluminum is increasing rapidly, bauxite reserves, currently estimated at 40 to 75 billion metric tons, are projected to last for centuries. Guinea and Australia have the two largest proven reserves.
In 2014 global aluminium production have reached 54 mln tonnes. The ex-China aluminium market was in shortfall of 1.2 million tonnes. According to CRU and International Aluminium Institute in the first half of 2015 aluminium production in the world outside ex-China grew by 2% YoY to 13 million tonnes.
Nov 09, 2010· Of all the earth's natural elements, aluminum happens to be the third most abundant resource on our planet in its raw form. With rather humble origins as a soft, red, mineral-laden rock called bauxite, highly valuable aluminum ore contains boehmite, diaspore and gibbsite as well as clay, iron hydroxides and free silica.
There are currently five bauxite mines in Australia providing feedstock for the seven alumina refineries, which in turn supply alumina to the six Australian aluminium smelters and the export market. Australia is the largest producer of bauxite in the world, with 74.9 million tonnes produced in 2011.
Aluminium is made by crushing and refining bauxite - an aluminium ore - into a white alumina powder then smelting the white alumina powder into aluminium metal. The smelter uses alumina predominantly imported from Worsley Alumina in Australia to produce high-quality, primary aluminium for the export and domestic markets.
This list of mines in Australia is subsidiary to the list of mines article and lists working, defunct and planned mines in the country organised by primary mineral output. For practical purposes, this list also contains stone, marble and other quarries.. As of October 2012, there were 405 operating mines in Australia.
Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
Mining of ilmenite began in the mid-1950s near Bunbury in southwest Western Australia. Today, Western Australia is the largest producer. To mine these minerals, sands are dredged through a large suction pipe and the heavy minerals are separated from the lighter sand particles.
Jul 23, 2015· Globally, Australia is the largest producer of bauxite and second largest producer of alumina but only a minor producer of the final product, aluminium, as highlighted in the graphs below.
According to the latest data on various mining job sites and resource sector job boards, mining job salaries in Australia vary between $77,000 and $240,000 annually. iMINCO has put together a list of some of the common mining jobs with an expectation of what you could expect to earn in a mining job.

This is more than all other non-ferrous metals combined. Australia mines bauxite in Queensland, Western Australia, the Northern Territory and Tasmania and is the world's largest bauxite producer. Australia is also a world leader in the production of alumina and aluminium.
Jun 06, 2019· Australia is the world's leading producer of bauxite, an aluminium ore that is used as the primary source of the metal. A Bauxite mining facility in Queensland, Australia. Bauxite is a soft limonite iron ore rock with portions of its iron composition replaced by aluminum. Bauxite forms when silica ...
Alcoa of Australia Ltd operates one of the world's largest integrated bauxite mining, alumina refining and aluminium smelting system and supports approximately 4,275 direct jobs, predominantly in regional Australia. Our operations consist of two bauxite mines, three alumina refineries and two dedicated port facilities in Western Australia and Portland Aluminium smelter in Victoria.
Australia was the leading producer of bauxite (Table 2) globally in 2012, the second largest producer of alumina and the fifth largest producer of aluminium. Indonesia was the largest exporter of bauxite because the majority of Australian bauxite is processed within Australia to alumina and aluminium. Table 2: World production for bauxite.

Africa leading the Way with Bauxite Production. Bauxite is an aluminium ore. It is known for being the main source of aluminium in the world. Bauxite was first discovered by a French geologist called Pierre Bertheir in 1821 in Provence in the South of France in Les Baux village.
British foundry specialist Aeromet International revealed earlier this week the latest strength test results for its patented additive manufacturing aluminium alloy A20X, noting that the alloy has now been confirmed as one of the strongest additive manufacturing powders currently commercially available.
The study shows that the level of risk associated with the use of aluminium alloys in underground coal mines in the United States of America is extremely low (high uncontrolled use - no ignitions). It is proposed that where similar equipment and conditions exist in underground coal mines in Australia, the level of risk is comparable.
