The property of some kind of Cu-Pb-Zn poly-metallic sulfide ore was studied in this paper.Aiming to the proper-ty of the ore and the existing problem of the dressing plant, the process of Cu-Pb-Zn priority flotation and lead rough con-centrate regrinding was adopted.According to the measures of pH regulation, high efficiency collector and combined de-pressant, rough concentrate regrinding were applied.copper concentrate containing Cu 22.34%with copper recovery of 67. 85%, lead concentrate containing Pb72.34%with lead recovery of 67.85%, zinc concentrate containing Zn50.55%with zinc recovery of 67.85%were obtained while the content of copper ,lead, zinc were 0.27%,2.07%,3.82%respectively in the raw ore.This Cu-Pb-Zn poly-metallic sulfide ore was separated in good index.
