Present Situation on Beneficiation of Lead-Zinc Oxide Ore

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 review of zinc oxide mineral beneficiation using

 · At present zinc is produced from zinc sulfide minerals which are the primary source of zinc and it is easy to separate the sulfide minerals from the gangue using conventional flotation techniques. As sulfide ores become depleted with the passage of time the beneficiation of oxidized zinc ores has assumed great importance in recent years.
