Bauxite Mines an overview ScienceDirect Topics

Approximately 98% of the alumina produced worldwide is manufactured via the Bayer process, which consists of digestion and calcination. Initially, the bauxite is washed and ground. During digestion, the bauxite is dissolved in caustic soda (sodium hydroxide) at high pressure (40–220 bar) and at high temperature (120–300°C).

Reasons For Bauxite Beneficiation Hatch Ltd

Adopting the process of washing bauxite in the beneficiation plant can reduce caustic soda consumption and equipment and piping scale in the alumina refinery (OPEX), and consequently the payback for the beneficiation plant can be less than 3 (three) years.
