    For refining bauxite to alumina, transportation and conversion costs are important; for smelting alumina to aluminum, energy costs are paramount. 6. Aluminum companies choose the loion of the refinery with a view to minimize the total cost of alumina production. To do so, they compare the cost of refining close to the mining site—largely energy . 6. Bauxite is mined .

    Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O .
