Flotation Separation Mechanism of Kyanite Group Minerals and Quartz:A Computational Chemistry Simulation
The crystal structure and surface properties of minerals and the mechanism of interaction between minerals and flotation agents were systematically analyzed by means of quantum chemical calculation and molecular dynamics simulation.Meanwhile,the flotation mechanism of kyanite minerals and quartz was discussed.The results show that the differences in the surface properties of kyanite,andalusite,sillimanite and quartz determine the differences in floatability,and citric acid can increase the floatability difference between kyanite minerals and quartz.The simulation result of computational chemistry is consistent with the experimental result of flotation.
