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 ...
Iron-stained titanium dioxides are removed by magnetc seperation, selective flocculation, and froth flotation. Organics are typically oxidized using ozone, which breaks down the discolored organic molecules and makes pigmentary iron oxides available for removal be reductive leaching.
The mashing operation can disperse the ore. Prepare the appropriate fine kaolin slurry for the sorting operation, and remove the large sand at the same time. The beneficiation stage may include hydraulic grading, flotation, selective flocculation, magnetic separation, chemical treatment (bleaching), etc. to remove different impurities.
The iron removal processes can be categorized as physical, chemical or a combination of both such as sieving, magnetic separation [8,9], EDTA [10], selective flocculation [11], carbohydrates [12], leaching with various chemicals like oxalic acid and other organic acids [13–23], organic acids in …

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 ...

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 ...
The selective flocculation tests carried out on 1:1 iron oxide/kaolin mixtures using parent polyacrylamide, polyacrylic acid and the modified polyacrylamide, confirm the possibility of enhancing selectivity through introduction of iron chelating functional groups in commercially available polymers.
