Beneficiation of diasporic-bauxite ore by selective ...

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.

A process which uses selective flocculation with hydroxamates for the beneficiation of mixtures of mineral particles (such as kaolin clays). The increased selectivity of hydroxamates for certain mineral phases within kaolin clays and other mixtures of mineral particles improves the process over selective flocculation processes utilizing other activators.
