Unlocking Australia’s nickel . Aluminium ore processing. We have developed a process that lowers the cost of refining bauxite to alumina by treating the waste product generated—red mud—to recover a costly ingredient, caustic soda. Dry slag granulation.
Alumina Refining. Alumina refineries process bauxite ore to produce alumina, which is then used to extract aluminium metal. Australia is the
The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and subtropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with
Productions of these three metals generate large quantities of waste during processing, particularly the gold production which is estimated to release 99% of the
Aluminium is made from bauxite, or aluminium ore. Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium.
The Bayer process is applied to extract aluminium from bauxite, whereas it generates a solid residue, which is known as bauxite residue or red mud. Australia has the largest
aluminum processing, preparation of the ore for use in various products. Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a
Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are more common. Earth’s crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to

Source Geoscience Australia. Australia produces 19 useful minerals in significant amounts, from over 350 operating mines. From these minerals, useful materials such as metals can be extracted. Australia is
Aluminium is both an important input to a number of technologies critical to the energy transition, and a significant source of CO 2, responsible for about 3% of the world’s 9.4 Gt of direct industrial CO 2 emissions in . In
The Bayer process is applied to extract aluminium from bauxite, whereas it generates a solid residue, which is known as bauxite residue or red mud. Australia has the largest primary reserves of aluminum ore (bauxite reserves): (USGS, ). Australia was the leading producer of bauxite in the world with 30% of global bauxite production.
Other world’s top 10 largest aluminium producing countries in include India, Russia, Canada, UAE, Australia, Bahrain, Norway, the U.S., and Iceland. Together, these top 10 largest aluminium producers account for over 85.6% of the world’s total aluminium production volume every year, and their leading position in the global market is
Armand Dufrénoy names the ore “beauxite” 1861: Henri SainteClaire Deville renames it as “bauxite” 1854: SainteClaire Deville discovers a method to separate kilogram amounts of aluminium from its oxide,
The aluminium production process is much more complex and requires huge amounts of electricity. For this reason, aluminium smelters are always built in the vicinity of power energy sources, usually hydroelectric power
Introduction. Aluminum is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in
The HallHeroult process is widely used in the extraction of aluminium. In HallHeroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering the melting point of the mixture and

Alumina Refining. Alumina refineries process bauxite ore to produce alumina, which is then used to extract aluminium metal. Australia is the second largest producer of alumina in the world (21.0 Mt in ).
Most of our assets are in Australia and North America, with operations also in Europe, Asia, Africa, and Central and South America. To produce aluminium, copper, diamonds, gold, industrial minerals and iron ore, we own and operate open pit and underground mines, mills, refineries, smelters, power stations, research and service facilities.
Aluminium is both an important input to a number of technologies critical to the energy transition, and a significant source of CO 2, responsible for about 3% of the world’s 9.4 Gt of direct industrial CO 2 emissions in . In
The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France where the ore was originally discovered. Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa.
