    Development Of Modified Bayer Process Kairyo Bayer

    Jun 05, 1998 In the conventional Bayer process, approximately 50 of alumina is extracted out of bauxite by use of caustic soda. Although most of the caustic soda is recycled, soluble silica approximately 3-4 in percentage that is extracted together with alumina reacts with the caustic soda and alumina in a desilication process, and this consumes some caustic soda.
