How can you separate alumina from silica in bauxite ore ...

To separate alumina from silica in bauxite ore associated with silica, first the powdered ore is digested with a concentrated NaOH solution at 473 523 K and 35 36 bar pressure. This results in the leaching out of alumina (Al 2 O 3) as sodium aluminate and silica (SiO 2) as sodium silicate leaving the impurities behind.
