The grade of fluorite in superconducting concentrate is increased from 85.21% to 96.84% and the grade of rare earth is decreased from 5.29% to 0.11% after the fluorite flotation concentrate of Bayan Obo Iron Mine is processed by superconducting magnetic separation technology. The grade of fluorite in fluorite flotation concentrate of Bayan Obo Iron Mine can be effectively improved, content of rare earth is decreased, flotation process of fluorite concentrate is shortened, amount of reagents and other power consumption are reduced with the superconducting high gradient magnetic separation so that the costs are effectively saved.
