Bauxite Extraction | .alteo-alumina

Today, more than 95% of alumina is produced from bauxite using the Bayer process. Bauxite is the ideal raw material because it contains alumina in a non-combined form and in great quantities (30% to 65%). The Bayer process conditions will vary depending on the type of bauxite that is used.

Extraction Process of Aluminium from Bauxite Ore

The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue.
