Bauxite is the primary ore used to make aluminium. Around 85% of bauxite is used to produce aluminium, 8% is used to produce alumina chemicals and 7% is used for abrasives, refractories, proppants and in cement. Depending on the ore grade, 4-6 tonnes of bauxite are required to refine into 2 tonnes of alumina, which in turn is smelted to make approximately 1 tonne of aluminium metal.
Most of the world’s bauxite comes from surface mines in tropical and sub-tropical areas, where bauxite typically occurs in extensive relatively thin near-surface layers, normally beneath a few meters of overburden. Because bauxite deposits often cover a very large area, bauxite mining involves disturbance of comparatively large land areas compared to the mining of other minerals. Only a small proportion of global bauxite is produced from underground mines.
