Chat OnlineFroth Flotation Process Used in the Lead Zinc Sulfide Ore
2020-2-20 · The iso-flotation process used in lead-zinc sulfide ore is to divide the lead and zinc sulfide ore with similar floatability into two parts easy-to-float part and difficult-to-float part. Then the mixed concentrate is obtained by the mixed froth flotation process which is separated as the single concentrates of various useful minerals successively.
