The invention relates to a method for improving grades of fluorite ore concentrate and rare earth ore concentrate of baiyuneboite through high-gradient superconducting magnetic separation. Fluorite ore concentrate graded from baiyuneboite is subjected to magnetic separation through a high-gradient superconducting magnetic separator by a high-gradient superconducting magnetic separation technology,so that the grade of CaF2 in the fluorite ore concentrate is improved to 90-99%, a mineral separating index of fluorite of the baiyuneboite is improved, and rare earth enrichment is obtained at the same time. The superconducting magnetic separation method is similarly suitable for rare earth ore concentrate products in the baiyuneboite, the grade of REO in the rare earth ore concentrate is improved to be more than 60%. According to the high-gradient superconducting magnetic separation technology, the simpleness and the high efficiency are realized, the occupied area is small, the power consumption is small, the cost is low, no chemical agent is used, water is directly recycled, and the environmental friendliness is achieved; and according to the method for improving the grades of the fluorite ore concentrate and the rare earth ore concentrate of the baiyuneboite through the high-gradient superconducting magnetic separation, the concentrate grades of the fluorite ore concentrate and the rare earth ore concentrate of the baiyuneboite are greatly improved, and the technical problems that the grade of the fluorite ore concentrate sorted from the baiyuneboite is low and the inclusion content of weak magnetic mineral rare earth is high are effectively solved.
