The invention relates to the technical field of hematite reverse flotation tailings, in particular to a hematite reverse flotation tailings re-election process, which is characterized in that the stage grinding of lean hematite, magnetic separation-gravity separation-anion reverse The reverse flotation tailings in the flotation combined process are re-selected, that is, the reverse flotation tailings are concentrated, then ground to a particle size of -320 mesh with a content of more than 90%, and then subjected to weak magnetic separation, strong magnetic separation-reverse flotation Operation, recovery of magnetic minerals in the reverse flotation tailings, the advantages of the present invention: firstly, the reverse flotation tailings are concentrated and defoamed to reduce the foam in the pulp, which is beneficial to the subsequent sorting operation. The reverse flotation tailings after concentration and defoaming undergo regrinding, weak magnetic, strong magnetic, reverse flotation operations of roughing, selection and three-stage sweeping to decompose the coarse-grained intergrowth monomers in the reverse flotation tailings Separation, separation and recovery of metals in reverse flotation tailings, reducing metal loss and lowering the final tailings grade. The process is simple, the number of equipment is small, and the occupied area is small.
