Bauxite Refractory Process Calcination

The bayer process the bayer process is the principal method for the production of alumina from bauxite worldwide.The modern version of the process developed in the 1880s still maintains the key steps of dissolution of alumina-rich minerals into hot caustic solution, separation of the insoluble phases, followed by gibbsite precipitation and calcination of the gibbsite to alumina al2o3.
