Abstract: Experiments on beneficiation of low grade lead-zinc sulfide ore in Yunnan were carried out with differential flotation under the selected reagent scheme for separation and recovery of lead and zinc minerals. The results demonstrate that the raw ore with 1.29% Pb and 5.63% Zn has the characteristics of valuable minerals being closely intergrown and finely disseminated. Good technical indexes of lead concentrate with 51.56% Pb grade at 78.58% recovery rate, and zinc concentrate with 46.12% Zn grade at 78.36% recovery rate are obtained, and lead and zinc minerals are effectively separated.

Key words: lead-zinc sulfide ore, differential flotation, lead, zinc, separation

摘要： 对云南某低品位铅锌硫化矿进行了选矿工艺实验研究，采用优先浮选工艺和所选药剂制度处理该矿石. 结果表明，该矿具有有价矿物共生关系紧密、嵌布粒度细的特点，其铅、锌品位分别是1.29%和5.63%，实现了铅、锌分离，获得铅品位、回收率分别为51.56%和78.58%的铅精矿和锌品位、回收率分别为46.12%和78.36%的锌精矿.
