With the exhausting of lead–zinc sulphide ores, the recovery of leadzinc 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 leadzinc oxides are difficult to recover.
