Bauxite mining in Australia - Wikipedia

CachedMining. 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.

Bauxite Mining The Australian Aluminium Council

CachedBauxite Mining. Scrapers and small excavators are used to remove the remaining overburden and expose the caprock. Depending on the depth of the caprock, it can be broken by blasting, or simply removed with scrapers and excavators. The bauxite is then mined using excavators or loaders to load the bauxite onto haul trucks and transported to the crusher.
