  • 4 Beneficiation Processes to Obtain Aluminum from Bauxite

    4 Beneficiation Processes to Obtain Aluminum from Bauxite

    Jul 29, 2020 Bauxite is mainly used to extract aluminum. About 85% of bauxite can be refined into alumina and then smelted into aluminum, 8% for chemical alumina, and 7% for refractory materials, proppants, and cement. Because of different grades of the ores, you can get 2 tons of alumina from 4-6 tons of bauxite and 1ton aluminum from 2 tons of alumina.
