Mining bauxite. Bauxite is usually found near the surface of terrain and can be strip-mined economically. The industry has taken a leadership role in environmental conservation efforts. When the land is cleared prior to mining, the topsoil is stored so it can be replaced during rehabilitation. During the strip-mining process, bauxite is broken ...
By 2040, the capacity gap was expected to increase to 83 Mt, demonstrating a long-term need for investment in bauxite mining capacity.

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.
