Bayer process

During this stage of Bayer process, aluminium crystals are filtered to separete them from the caustic liquid

During this stage of Bayer process, the slurry is heated to 270°C forming a supersaturated sodium aluminate solution

During this stage of Bayer process, bauxite residue settles at the bottom and is washed and filtred prior to disposal

During this stage of Bayer process, small bauxite particles are mixed with heated solution of caustic soda, creating slurry

During this stage of Bayer process, alumina hydrate is heated to 1100 °C to remove the bonded water moleculs producing aluminium oxide (the hemical name of alumina)

During this process of Bayer process, filtred liquid is cooled down and treated with seed crystals wich help crystalisation, forming aluminium hydrate

Durinag this stage of Bayer process, bauxite ore is crushed to reduce its parts size.
