  Advances in Beneficiation of Low-Grade Bauxite

  Bauxite is the major alumina (Al2O3) bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50% Al2O3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. The alumina-silica and alumina-ferrite complexes are the foremost impurities present in the …
