The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentratedsolution of sodium hydroxide. The NaOH will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.
