Advances in Beneficiation of Low-Grade Bauxite

2019-2-16 · Abstract. Bauxite is the major alumina (Al 2 O 3) bearing ore used in the aluminum manufacturing industries.The bauxite containing less than 50% Al 2 O 3 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 low-grade bauxite.
