BAUXITE AND ALUMINA—2000 11.1 BAUXITE AND ALUMINA ... Bauxite was used mainly for the manufacture of aluminum, although a considerable quantity was used for the manufacture of aluminum sulfate and crystalized alum. In order to produce aluminum commercially, bauxite was converted to alumina by the Bayer
The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell.

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.
Bauxite718 Кб. Depending on the grade and mineralogy of the bauxite used, the industry standard is that it takes approximately 4–6 t of dried bauxite to produce 2 t of alumina, which in turn yields 1 t of aluminum metal.
Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties. It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed.
