| Abstract: |
| For a low grade copper-lead-zinc sulfide ore, the flotation separation experiment was carried out by the process of preferential flotation of copper-lead—zinc-sulfur mixed flotation and zinc-sulfur separation. A high-efficiency and selective copper collector BK916 and lead collector BK906 were used to conduct a copper-lead sequential preferential flotation test study. In the experimental study of zinc-sulfur separation, the combination of environmental protection inhibitor BD and lime effectively inhibited the pyrite in zinc-sulfur mixed concentrate. It can obtain copper concentrate with copper grade of 20.68% , copper recovery rate of 72.98%, and lead concentrate with lead grade of 61.38%, lead recovery rate of 73.57%, and zinc concentrate with zinc grade of 46.31%, and zinc recovery rate of 73.17%, and sulfur concentrate with sulfur grade of 48.54%. |
