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. Much of the topsoil is stored, conserving seeds, vegetation and soil for rehabilitation when mining operations finish. Once the overburden is cleared, excavators and front-end loaders mine the exposed bauxite ore. It is then loaded into

Australian Bauxite | The Australian Aluminium Council

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. The major Australian bauxite mines are: Boddington (Western Australia) – South32; Gove (Northern Territory) – Rio Tinto Aluminium

Tacey 1979). The bauxite is mined using front-end loaders, power shovels, or hydraulic excavators and loaded in large trucks that can carry 50 to 100 tones. Australian bauxite is considered low grade and it takes 3 to 4 kg of bauxite to produce 1 kg of alumina (Hickman et al. 1992). Blasting is sometimes done to break-up cemented-cap rocks.

In 1992, bauxite EDR decreased as a result of the reclassification of some resources on Cape York Peninsula to comply with requirements of the Joint Ore Reserve Committee (JORC) Code ('b' in Figure 2). Since 1992, Australia's bauxite EDR has steadily increased and in recent years has remained steady at around 6000 Mt.

Bauxite is an aluminium ore found in deposits around the world. Once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the Bayer process. This alumina powder is then smelted into aluminium metal. Australia is the world’s largest producers of bauxite.
