| Abstract: |
| The lead minerals and zinc minerals are difficult to separated for fine disseminated size in a low-grade Pb-Zn ore of yunnan. For the purpose of comprehensive utilization of these resources,selective flotation process was adopted under the grinding fineness of -0.074 mm 85％by detailed beneficiation test research-adding composite inhibitors to float lead and depress zinc,finally obtaining the lead concentrate with grade of Pb 55.38%, the recovery of Pb 79.56% and zinc concentrate with grade of Zn 50.23% and the recovery of Zn 91.36% . The mineral processing indexes were excellent,finally realized the high effective separation of Pb and Zn． |
