Advances in Beneficiation of Low-Grade Bauxite
Aluminum industries use bauxite as the major raw material . Bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore, which is generally used for the production of aluminum appliances such as abrasives, ceramics, and refractories . The presence of impurities, including silica, iron oxides, and calcium contribute to the …
