  • ARTICLE Addressing the Challenge of Bauxite Residue

    ARTICLE Addressing the Challenge of Bauxite Residue

    Bauxite ore contains 30-60 aluminum oxide Al 2 O 3. In the Bayer process Figure 2, the bauxite is digested in a pressure vessel along with a sodium hydroxide solution caustic soda at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.

    The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240C the pressure is approximately 3.5 MPa. The slurry is then cooled in a series of flash tanks to around 106C at atmospheric pressure and by flashing off steam. This steam is used to preheat spent liquor.
