摘　　要：针对云南兰坪地区某高泥型硫氧混合铅锌矿开展选矿技术研究。在工艺矿物学分析的基础上,结合了常规氧化锌选矿难点,确定了预先脱泥—泥质重选回收氧化锌—先硫后氧浮选回收铅锌的"重—浮"联合回收工艺。研究使用离心机有效地回收了泥质中的氧化锌矿物,氧化锌浮选采用新型组合捕收剂改善了氧化锌矿物分选效果,全套技术成功地应用于该矿山生产,取得了优异的工业生产指标。The beneficiation technology study on a high-mud sulfide-oxide Pb-Zn ore in the Lanping area,Yunnan is presented in this paper.Based on the process mineralogy study and considering difficulties associated with conventional processing methods,a combiation process of gravity-concentration-and floation,which includes predesliming,recovering of zinc oxide from muddy by gravity concentration,lead and zinc sulphides floataion followed by oxides flotation,was determined.The study used the a centrifuge to recover zinc oxide effectively,and the new combined collectors improved the flotability of zinc oxide in flotation processes.The full set of technology was successfully applied to the mine production,and achieved excellent industrial production indices.
