RM, also named bauxite residue, is the major waste produced during the alumina production process . Depending on the quality of the bauxite and its processing, about 15–40% of processed bauxite ore enters the waste in the form of alkaline slurry . It is estimated that 1.0–1.5 t of RM was generated when produced 1 t of alumina [7,8].
