摘　　要：某银铅锌矿石主要有价元素为银、铅、锌。通过原矿工艺矿物学研究及小型试验研究,确定了适合该矿石性质的全优先浮选工艺流程及最佳的工艺条件。优先浮选银铅再浮选锌的小型闭路试验获得了铅精矿铅品位51.38%、铅回收率92.32%,银品位2 078.0 g/t、银回收率74.36%,锌精矿锌品位48.64%、锌回收率80.81%的良好指标。Silver, lead and zinc are the main valuable elements of one silver - lead - zinc ore. Selective flotation and the optimal technical conditions were chosen based on the study of process mineralogy and experimental research on the raw ore. A good index was obtained in a small scale closed circuit experiment with the lead grade of lead concentrates being 51.38 %, Ag grade 2 078.0 g/t,lead recovery rate 92.32 %, silver recovery rate 74.36 %, zinc grade of zinc concentrate 48.64 % ,and zinc recovery rate 80.81%.
