The loss of expensive caustic soda NaOH and the generation of red mud are both related to the quality of the bauxite used in the refining process. In general, the lower the Al2O3 content of the bauxite, the larger the volume of red mud that will be generated, as the non-Al2O3 phases are rejected as red mud.
