2008-8-1 · The beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with Na 2 CO 3 and PAS at pH about 9–10, but it is sensitive to the content of kaolinite. For the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the Al 2 O 3 recovery of 87.0% and Al 2 O 3 /SiO 2 ratio of 8.9.
