The Bayer refining process used by alumina refineries worldwide involves four steps: digestion; clarification; precipitation; and; calcination. 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. The solution is then cooled in a
