TENORM: Bauxite and Alumina Production Wastes Radiation ...

Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina. Finally, hydrated alumina is crystallized and calcinated (dried in a furnace) to produce solid alumina.

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.
