The iron ore concentrate with grade of 64.22% and recovery rate of 77.69% could be obtained by taking the process of weak magnetic separation-strong magnetic separation-reverse flotation to the middle low grade ore stacked in a polymetallic mine; the rare earth ore concentrate with grade of 55.85% and recovery rate of 60.08% could be obtained by taking the process of direct flotation with one-time rougher flotation and three-time concentration to the tailings of high intensity magnetic separation; the fluorite concentrate with grade of 91.7% and recovery rate of 29.67% could be obtained by taking the process of one-time rougher flotation and six-time concentration-strong magnetic concentration to the tailings of rare earth ore beneficiation.
