The Bayer process is essential for refining bauxite into alumina (aluminum oxide), the precursor for aluminum production. This process involves several key steps: Hydrothermal Digestion and Clarification. First, bauxite ore is ground and mixed with a hot, concentrated solution of caustic soda (sodium hydroxide, NaOH) in digesters under pressure.

Bauxite residue, well known as red mud, a by-product of alumina industries, bauxite is used as a chief ore. Nearly 95% of the alumina is produced from Bayer's process, and only the remaining 5% is from sintering or combined process [1, 2].Per every 1 ton of aluminum, around 1–1.5 tons of red mud is generated by consuming 2–3 tons of bauxite [2,3,4].
