Bauxite Mining Australian bauxite deposits generally have high grades and are shallow and relatively easy to mine. Bauxite mining is a relatively simple process with only minor processing requirements (crushing / beneficiation) and as such, bauxite mining is not very emissions intensive. However, as a surface mine, haul distances can be ...
