Bauxite ore is the primary raw material that is refined into alumina and later sent to our smelters where it is processed into aluminum. Our leading position in mining is built on our ability to meet customer-specific needs for high-quality, sustainably produced material.
Yarwun. Australia. 213. Queensland Alumina Limited (QAL) commenced production in March 1967 with an annual production rate of 600,000 tonnes of alumina. Today it is one of the world's largest alumina refineries, producing almost 4 million tonnes of the world's best smelter grade alumina per year. The refinery covers 80 hectares of a 3,050 ...
Australia is the second largest producer of alumina in the world, with around 15 per cent of global production from six alumina refineries. As water is a key input for refining bauxite into alumina, Australian alumina refineries are located in areas with reliable water supply.
Rio Tinto is the largest bauxite miner in Australia and reported production of 54.3 million tonnes (mnt) of bauxite from all its mines for 2021, down 3 per cent from the previous year primarily ...

The major Australian bauxite mines are South32's Boddington mine in WA, Rio Tinto's Gove operations in the Northern Territory and its Weipa mine in Queensland, and Alcoa's Huntly mine and Willowdale mine in WA. Australia usually exports a third of its bauxite production while the remainder is converted to alumina.
This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure. The sodium hydroxide dissolves the aluminum oxide, forming sodium aluminate. The iron oxide remains solid and is separated by filtration.
The initial capacity of the plant was a (relatively) meagre 12 kilotonness (kt) per year, with all the bauxite used imported. Today, the Australian aluminium smelting and alumina refining ...
Our Gove Operations – including the township of Nhulunbuy – are located on Aboriginal land. We acknowledge the significant value Yolngu place on their heritage and Country, and work in partnership with them throughout the mining process to manage this.
Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then removed, leaving the process liquid, termed "green liquor."
Australian Bauxite. There are currently six bauxite mines in Australia providing feedstock for the six alumina refineries and the export market. These alumina refineries, in turn, supply alumina to the four Australian aluminium smelters. Australia is the world's largest producer of bauxite. In 2021, Australian bauxite production was 101 ...
Rio Tinto is a global leader in aluminium, one of the world's most widely used metals. Active in the sector for more than 110 years, today we operate large-scale, high-quality bauxite mines and alumina refineries and the world's most modern and competitive aluminium smelters portfolio. Learn more with Rio Tinto.
Australia is the world's largest producer of bauxite, mining more than 100Mtof bauxite a year, or about a quarter, of global production. About 40% of this is exported and 60% is turned into alumina here in Australia. We are the world's second largest producer and largest exporter of alumina, with production of more than 20Mt a year.
Our Gove Operations in Australia's Northern Territory have been supplying the global aluminium industry with world-class bauxite for more than 40 years.. Gove bauxite is shipped internationally as well as domestically to supply Queensland Alumina Limited and Yarwun refineries in Gladstone, Queensland. These refineries produce alumina as feedstock for our Australian aluminium smelting ...
Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties
Australia 213 Queensland Alumina Limited (QAL) commenced production in March 1967 with an annual production rate of 600,000 tonnes of alumina. Today it is one of the world's largest alumina refineries, producing almost 4 million tonnes of the world's best smelter grade alumina per year.
1See also Aluminum. As a general rule, 4 tons of dried bauxite is required to produce 2 tons of alumina, which, in turn, produces 1 ton of aluminum. 2Includes all forms of bauxite, expressed as dry equivalent weights. 3Defined as production + imports – exports + adjustments for industry stock changes.
Alcoa's bauxite primarily supports our internal alumina refinery system, and we also supply global, third-party customers. Ownership positions in seven mines globally, including the Huntly mine in Australia, the world's largest bauxite mine. Strategically located global network near key Atlantic and Pacific markets.
Alumina Refining. Alumina is a white granular material, a little finer than table salt, and is properly called aluminium oxide. Aluminium does not occur as a metal but must first be refined from bauxite into alumina. Approximately two tonnes of alumina are required to produce one tonne of aluminium. Australia is the second largest producer of ...

All heritage features and values are considered as being of equal value. If a site or an object is identified as significant, it is protected from mining. For example, in 2021, 148 hectares of land were surveyed across the Gove mining lease with the Gumatj and Rirratjingu Traditional Owners to protect and preserve sites and story places.

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. The three Western Australian refineries supply 45% of Australia's ...
Bauxite is mined from reserves mainly within State forest on the eastern edge of the Darling Range, near Boddington. The bauxite is crushed and carried 51km by a two-flight cable belt conveyor system to the refinery site at Worsley. It is then processed, and the separated alumina is carted by rail and exported through the Port of Bunbury.
Western Australia's bauxite reserves are estimated to be capable of sustaining more than 50 years of alumina production at current levels. The State's main two alumina producers are Alcoa of Australia and South32's majority owned Worsley Alumina. Western Australia accounts for 33 per cent of Australia's alumina production. Uses
