Present Situation on Beneficiation of Lead-Zinc Oxide
With the exhausting of lead–zinc sulphide ores, the recovery of lead-zinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the lead-zinc oxides are difficult to recover.

A possible difference in the flowsheet might be the addition of a gravity preconcentration stage for lead. In some cases, the heavy liquid separation is performed prior to lead zinc oxide flotation. The reagent scheme selection is very dependent on (a) type of gangue minerals present in the ore and (b) type of lead and zinc oxide minerals.
