EXPERIMENTAL STUDY ON FLOTATION TECHNOLOG OF SOME COMPLEX LEADZINC OXIDE ORE IN YUNNAN

On the base of the process mineralogy researching of the lead-zinc ore in Yunnan,the principle flowsheet is sulfide flotation and then oxide flotation,first lead and then zinc.What’s more,heating and the agent YXL as the assistant collector was used in flotation of zinc oxide mine.The non-desliming flotation flowsheet has got a better classification index: the total zinc recovery was 83.26%,which consist of 16.69% zinc sulfide and 66.57% zinc oxide,the zinc sulfide concentrate grade was 50.38% and the zinc oxide concentrate grade 22.29%.The total lead recovery was 56.37%,which consist of 530.61% lead sulfide and 25.76% lead oxide;the lead sulfide concentrate grade was 50.86% and the lead oxide concentrate grade was 49.15%.
