The bauxite then has to be purified using the Bayer process, whose development changed the course of aluminium's history. The process occurs in two main steps. Firstly the aluminium ore is mixed with the sodium hydroxide in which the oxides of aluminium and silicon will dissolve, but other impurities will not.These impurities can then be removed by filtration.he process occurs in two main steps.
