of sulphide minerals flotation separation was analyzed. Three charge transfer models of electrochemistry reaction taking place on mineral particle′s surface were proposed for different system of sulphide flotation, which were model of charge transfer by particle itself, model of charge transfer on interface of mineral particle and liquid phase and model of charge transfer by the collision......
