Floatation separation and floatation separator is mainly involved for lead-zinc ore beneficiation because the enrichment efficiency of lead-zinc ore by floatation separation is high with mature flow sheet, and most lead-zinc ore is extracted by floatation separation. But with the development and exploitation of mines, more and more mines can not be meet the grade floatation separation required.
