Present Situation on Beneficiation of Lead-Zinc Oxide Ore

摘要

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. Eliminating the influence of slime and strengthening the study of joint process are the main development trends in future work.
