Mining and Refining Bauxite Residue Management

Bauxite residue is a by product of the Bayer Process. The caustic soda is recycled back into the digestion process, reducing production costs and in turn lowering the alkalinity of the residue. The pH level of the residue is generally up to 13 or higher in some cases, due to the presence of alkaline sodium compounds, such as sodium carbonate and sodium hydroxide.
