    Feb 22, 2008 · The Bayer process is the principal industrial means of refining bauxite to produce alumina. Bauxite, the most important ore of aluminium, contains only 30-54% alumina, Al2O3, the rest being a mixture of silica, various iron oxides, and titanium dioxide[1]. The alumina must be purified before it can be refined to aluminium metal.
