Abstract
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.Fe2O3 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.
