Bauxite mining in Australia - Wikipedia

Bauxite mining in Australia is an economically significant industry both for Australia and globally. The industry focuses on the mining of bauxite, the primary raw material for alumina and aluminium. Australia is the world’s bauxite producer, producing almost a third of global bauxite. Bauxite is mined in Australia using open-cut mining, which suits the relatively shallow bauxite deposits located mostly in Western Australia and Queensland. Mined bauxite is either exported or refineddomestica

Mining and Refining – Process

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Aluminium | Geoscience Australia

In almost all commercial operations, alumina is extracted from the bauxite by the Bayer refining process. The process, discovered by Karl Josef Bayer in 1888, consists of four stages. Digestion: the finely ground bauxite is fed into a steam-heated unit called a digester. Here it is mixed, under pressure, with a hot solution of caustic soda.
