Like most minerals bauxite is a mixture of several compounds it has to be refined by solvent fractionation to remove the acidic SiO 2 and amphoteric Al 2 O 3 from the basic Fe 3 O 4 and TiO 2 The process uses 30% NaOH in the Bayer process The iron and titanium compounds are removed as red mud and silicates crystallize out as Na 2 Si OH 6
