Abstract:

A low grade polymetallic lead-zinc ore with associated silver has the problems of low selective indicators and unreasonable pharmacy system.Based on a series of condition experiments of mineral processing after analyzing composition and ore properties of raw ore and ore proportioning，preferential flotation process of zinc floating lead was determined.The lead mine were successfully separated from lead-zinc mineral under the conditions of that the collector was the combined reagent which with 1∶1 ratio of the ammonium dibutyl dithiophosphate and butyl xanthate，sodium sulfide as the sulfur inducer，lime and sodium carbonate as inhibitors of pyrite and magnetite.Zinc sulfate and copper sulfate are used as inhibitors and activators of zinc respectively.Under the conditions of two roughing，three scavenging，three cleaning of closed-circuit experiments，lead concentrate with lead grade of 60.29%，silver grade of 826.13×10-6 and lead recovery rate of 92.02%，silver recovery rate of 72.75% was obtained.The zinc concentrate with zinc grade of 48.32%，silver 61.71×10-6，zinc recovery rate of 92.30%，silver recovery rate of 19.19% also was obtained.It shows that the process has good flotation index and it can be instructive for the selection of such kind of ores.

Key words: low grade, associated silver, polymetallic lead-zinc ore, combined reagent, sulfur inducer, priority flotation process
