Abstract:
     The invention relates to a floating method of sulfide-oxide mixing Pb-Zn mine. The lead floating method adopts the flow process of one fast separation, one roughing separation, one sweeping separation and three classifications so that the mine grouting acidity of the full floating process can keep at pH＞11. The zinc floating method adopts the flow process of one fast separation, one roughing separation, one sweeping separation and two classifications so that the mine grouting acidity of the full floating process can keep at pH＞12. It can increase the recovery ratio of Pb、Zn over 10% when Pb-Zn mine has oxide ratio over 30%.
