Australian bauxite, the primary ore for aluminium production, is mined through an open-cut mining process. Bauxite deposits are typically found close to the surface, so mining begins with the removal of overburden— the layer of soil, vegetation, and rock above the bauxite deposit. Heavy machinery, such as excavators and bulldozers, is used to ...
