Surface Electro-chemical Performance of Mud-mineral from Alumina Production and Selective Flocculation with Polymer Functional Group

The flocculation effects of the flocculates with different polymer functional group on sole silica suspension slurry and multi-suspension slurry are investigated,and the flocculation adsorption performances of the functional group with the hematite and silica in suspension slurry are analyzed.The more humic salt and organic impurity adsorption and the more clear settlement can be achieved by substitution of starch with the synthetic macro-molecular polymer flocculates.Some industrial technical conditions of suspension separation are obtained by the selection of the polymer.The surface electro-chemical property of the particles in the slurry is the foundation of selective flocculation.
