Kaolinite removal from bauxite by flotation

Bauxite ore was carefully prepared, by comminution operations and size separations, specifically to minimise fines generation. After that stage the ore was deslimed. The final size range of the bauxite sample was: -150 µm + 15 µm. The preparation of bauxite caused an increase in the alumina/silica mass ratio from 7.30 to 11.05.
