Extraction Process of Aluminium from Bauxite Ore - 911 MetallurgistMar 17, 2017 . 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. The aluminate solution is.bauxite beneficiation solution,bauxite beneficiation solution,Method of Hydrochemical Benefication of Bauxite Способ .A method of hydrochemical beneficiation of high-ferriferous, high- carbonated bauxites by processing of raw bauxite with solution of complexon in the medium of hydroxide under pressure has been developed.

The effects of apex diameter, feed pressure and feed concentration on separation indexes were tested, and then the separation process was discussed by hydrokinetics tentatively. The results show that the increase of apex diameter changes.
