Abstract:For the characteristics of the low grade of rare earth and fluorite, high mud content, complex composition and barite collector in a tailings dam, the mixed flotation method was used to recover the rare earth and fluorite, and the mixed concentrate was obtained, with rare earth grade of 18% and fluorite grade of 55.57%. The mixed concentrate was separated by wet high intensity magnetic process (rough, clean, refined；magnetic field intensity of 1.5T), and the final grade of rare earth concentrate was 68.42%, the recovery rate was 55.01%, and the grade of fluorite in the tailings was enriched to 79.39%.
