Application and Development of Depressant BK501 in the Desilication from Bauxite by Reverse Floatation

摘要：

Mechanism of BK501 in desiliconization from bauxite was studied by use of flotation test, EDS,ζ-potential, FTIR. Results of flotation show that almost all of diaspore can be depressed when BK501 is put into pulp ranging from pH 4～12, in the meanwhile kaolinite is slightly activated. In the light of surface analyses, it is concluded that the adsorption of reagent on the diaspore is dominant by chemical interaction. Moreover, kaolinite may float more by addition of BK501 because of flocculation.
