Australia. 213. Commercial quantities of bauxite were discovered on Aboriginal lands at Weipa in western Cape York in 1955. Nine years later commercial production began, with 453,365 tonnes of bauxite mined and shipped that year. By 2009, this annual production figure had increased to 16.3 million tonnes, mined by 745 full time employees.

Once washed, the ore becomes 'product' and is stored on stockpiles. Andoom product is transported to the stockpiles by train. Weipa bauxite mined by Rio Tinto in Queensland Australia is pisolitic, with the silica level (both kaolinitic and quartz) decreasing with increasing pisolite size.
Bauxite ore is a widespread rock mainly composed of aluminium hydroxide minerals. On the platform the companies provides various grades and types of the bauxite ore including raw bauxite and calcined bauxite. The most valuable element of bauxite is aluminium oxide (Al2O3.) The quality and grade of bauxite as aluminium ore depends on the content ...
Jan 29, 2014· Pisolitic bauxite ore is an ideal ore for various reasons. It is located close to the surface so very little cover is needed to be removed to expose it. The bauxite is loose and easily mined with front-end loaders. Beneficiation of the ore before it is shipped out …
In 1992, bauxite EDR decreased as a result of the reclassification of some resources on Cape York Peninsula to comply with requirements of the Joint Ore Reserve Committee (JORC) Code ('b' in Figure 2). Since 1992, Australia's bauxite EDR has steadily increased and in recent years has remained steady at around 6000 Mt.
The bauxite mines in the Darling Range have the world's lowest grade bauxite ore mined on a commercial scale (around 27-30% Al 2 O 3). Despite the low grade, the mines accounted for 23% of global alumina production. JORC-compliant bauxite resources also occur in New South Wales and Tasmania but these are small (<25 Mt).
— Guinea has the world's largest bauxite reserves and is the biggest exporter of the ore while Australia tops the world in mine production. — The Huntly mine in Australia, owned by Alcoa World Alumina, is the world's largest, producing 18 million tonnes in 2006.

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. Australia is the largest producer of bauxite, with five mines supplying around 23 per cent of global production.
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.
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.
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
