摘　　要：对滇东某多金属氧化铅锌矿采用先铅后锌的工艺浮选,浮选流程均为两粗一精一扫.结果表明,矿石中有价元素为铅、锌、银,铅主要赋存于白铅矿和铅矾中,锌主要赋存于菱锌矿和异极矿中,银以伴生形式存在,目的矿物嵌布粒度较细.浮选所得铅精矿铅品位为61.45%,铅回收率为86.41%,银品位为451.58 g/t,银回收率为66.73%,含锌3.68%;锌精矿锌品位为42.32%,锌回收率为90.63%,含铅1.39%.两性捕收剂R（144）对锌的捕收能力和选择性比十二胺、十八胺和二者混合胺更好.A selective flotation process of lead minerals was developed to a lead-zinc oxide ore in the eastern region of Yunnan Province, China. The flotation process with two roughing, one cleaning and one scavenging was adopted in the recovery of lead and zinc. The results showed that the valuable elements in the ore were lead, zinc and silver. The main minerals of lead cerussite and anglesite, zinc were smithsonite and hemimorphite respectively, and silver minerals associated mostly with lead minerals. The dissemination of valuable minerals was relatively fine. The lead concentrate grade was 61.45% with Pb recovery rate 86.41%, the grade of Ag was 451.58 g/t and the recovery rate was 66.73%, containing 3.68% Zn. The zinc concentrate grade was 42.32% and the recovery of Zn was 90.63%, containing 1.39% Pb. The amphoteric collector R144 showed better performance both in collecting ability and selectivity to zinc minerals than that of dodecylamine, octadecylamine and combined amines.
