Bauxite Residue In Australia - World Aluminium

Bauxite Residue In Australia What is Bauxite Residue? Bauxite residue, sometimes referred to as ‘red mud’, is the by-product of the Bayer process – an industrial chemical process for refining aluminium-containing ores in alumina (aluminium oxide), the raw material used to produce aluminium metal. In the Bayer process, bauxite ore is dissolved using

Bauxite mining in Australia - Wikipedia

In Australia, bauxite is mined using an open-cut method. This is possible because most bauxite in Australia can be found at or relatively close to the surface and is easily accessible by this method. Open cut mining involves first removing the area above the bauxite ore called the overburden.

Australian Bauxite The Australian Aluminium Council

There are currently five large bauxite mines in Australia providing feedstock for the six alumina refineries, which in turn supply alumina to the four Australian aluminium smelters and the export market. Australia is the world’s largest producer of bauxite. In 2019, Australian bauxite production was 101 million tonnes (Mt). 43 Mt of bauxite was exported, and the remainder converted to Australian alumina.
