    The DMS concentrate and crusher fines will be grinded in a single-stage ball mill with cyclone classification. Slurry from the mill will be fed to a two-stage selective flotation circuit wherein copper and lead will be separated to produce zinc concentrate. The zinc flotation concentrate will be thickened, filtered, and bagged for transport.
