  • EP0950020A1 - Removal of silica from bauxite - Google Patents

    A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial part of the reactive silica from the bauxite. The caustic liquor is selected to have a high caustic concentration and a high alumina content.

  • 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.
