Separation Of Diaspore From Bauxite By Selective
Apr 25, 2014 Selective flocculation is a new method to solve the problem of China’s bauxite de-silication besides flotation and reverse flotation. The method of selective flocculation of bauxite using hydrolyzed polyacrylamide as flocculant was experimented and evaluated. The results of diaspore and kaolinite single mineral settling tests show that the difference between settlement yield of kaolinite ...

Microbially Induced Selective Flocculation Of Hematite
Abstract Microbially induced selective flocculation of hematite from kaolinite has been demonstrated using Bacillus subtilis. Growth of bacterial cells in the presence of kaolinite resulted in enhanced production of extracellular proteins while that of hematite promoted significant secretion of exopolysaccharides. Bacterial cells were adapted to grow in the presence of the minerals and use of ...

Application Of Differential Bioflocculation In The
Abstract. Differential flocculation acts based upon the difference in the settling rates of two minerals. So, the application of the bacterial cells, spent medium, extracellular protein, and polysaccharide derived from a cell-free extract of Bacillus licheniformis were investigated to remove hematite and goethite from kaolin and quartz. The zeta potentials and settling behaviors of the ...
