Abstract: | A medium A/S ratio bauxite sample from Henan was chosen as the subject for the test.After systematic study,an efficient reagent system was work out,including dispersant BK500,selective depressant BK501 and selective collector BK421 for alumino-silicate.Qualified concentrate can be obtained at recovery of 81.20% Al2O3 with A/S ratio of 10.82 by process of twice desiliming and desilication by reverse flotation. |
