Activity Description
The production process of alumina via the Bayer process includes steps such as raw material proportioning and slurry preparation, pre-desilication, digestion, red mud separation, seeding decomposition, and aluminum hydroxide calcination.
Process Description
Aluminium oxide is an inorganic compound with the chemical formula Al2O3 and CAS number 1344-28-1. It has a melting point of 2054°C and a boiling point of 2980°C, and it is an ionic crystal that can ionize at high temperatures. Aluminium oxide can be used in the production of refractory materials, electronic substrate materials, and in the electrolytic production of metallic aluminium.

Technology comment
The Bayer process uses high-grade bauxite ore, which is mixed with alkaline solution, lime milk, and mother liquor in proportion and ground into slurry. Sodium aluminate is then directly leached under corresponding temperature and pressure conditions after pre-desilication, followed by red mud separation, seeding decomposition, and calcination of aluminum hydroxide to produce finished alumina. For high-grade ores with an aluminum-to-silicon ratio greater than 7, the Bayer process is the preferred production method.
