Abstract: The flotation role and benaviors of kyanite-group polymerphous minerals were studied in modified Hallimond tube in detail. Furthermore, the energy change of collector/mineral system before and after adsorption and the net charge densities of the atoms on the minerals surfaces were calculated by use of quantum chemistry. The flotabilities in minerals were successfully explained.
