Filter pressing and dry stacking convert bauxite residue into a more stable solid form, helping reduce environmental risks and improve waste-management efficiency.
Hydrate calcination is the final Bayer stage, converting aluminium hydroxide into alumina while controlling product quality, energy use, heat efficiency and emissions.
Alumina production is advancing through Bayer process optimization, digitalization, residue management and lower-carbon technologies to improve efficiency and sustainability.
