Alumina Refining
The Bayer refining process used by alumina refineries worldwide involves four steps: Step 1: Digestion . Bauxite is finely ground in mills, then mixed with a recycled caustic soda solution and steam in digester vessels operating at high temperature and pressure. This dissolves the alumina content of the bauxite.
