Explanation: 1. For concentration of bauxite ore, first it is taken in a ball mill. 2. There is is ground. 3. After grinding, it is leached by heating with concentrated caustic soda solution ( NaOH ) at 140 to 150 °C under high pressure for 2 to 8 hours in the digester.
Extraction of Aluminium From Bauxite, Bayer's & Hall's Process
21-12-2021· The concentration of the Bauxite ore into alumina is done by Bayer’s process. Alumina is then refined into pure aluminium metal through the Hall–Héroult electrolytic process. Aluminium is too high in the electrochemical series (reactivity series) to be extracted from its ore using carbon reduction.bayers process of bauxite concentration,20-08-2017· Bayer's process is used to obtain pure aluminium oxide from bauxite ore.
