Australia to remain global leader of bauxite production

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.

How Aluminum Works | HowStuffWorks

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.

Bauxite Mining and Alumina Refining - LWW

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."

Aluminium | Geoscience Australia

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
