Bauxite mining Bauxite is mined by opencast methods using the most modern large scale earth-moving equipment. The present emphasis is on blending to produce a uniform grade ore, the use of lower grade bauxite, and the maximisation of reserves. Mining is most commonly carried out using a benching method requiring power shovels and draglines.
