Alumina is produced in a totally separate first stage process from Bauxite ore. This (Bayer) chemical process starts by immersing crushed bauxite into a caustic soda solution which dissolves the alumina to form sodium aluminate liquor (Figure 1501.01.01). After filtering, the impurities are left behind as a "red mud" and the liquid is treated to
