Abstract

Abstract: Sedimentation method is used to study the sedimentation behavior of bauxite concentrate at different pH values and flocculants, and the effect law of anionic, non-ionic and cationic polyacrylamide flocculants, and the change in molecular weight of anionic flocculant on concentrate sedimentation. The results show that when the medium pH value is 7.0, anionic polyacrylamide flocculants have the best effect on flocculation results and the best dosage is 30 g/t.

Key words: Bauxite, Flocculation, Polyacrylamide
