According to the properties of the zinc leach residue, the recoveries of lead and zinc from residue have been studied in this paper. At first, ZnO.Fe_2O_3 was recovered by magnetic separator, and the grade of zinc concentrate is 14.89% and the recovery is 65%. Next step, zinc sulfide was recovered by flotation, and the grade of zinc concentrate is 29.65% and the recovery is 29.65%. The last, the lead residue was recovered by flotation and the grade of lead concentrate is 17.21% and the recovery is 56.37%. The technology is very effective to enrich value metals, and realize utilization of resource protecting the environment.
