摘　　要：针对某氧化铅锌矿嵌布粒度微细、氧化率高等特点,采用先硫后氧浮选工艺流程,得到铅锌混合精矿与合格锌精矿,然后采用新型氧化矿硫化剂EMS-3硫化氧化铅矿物,再浮选得到氧化铅精矿产品。采用该工艺流程,伴生的银在精矿中得到富集,使资源得到最大化利用。Directed at the characteristics of fine dissemination size and high oxidation ration of an oxide lead - zinc ore, the technological flowsheet of oxide after sulfide flotation was adopted. This leads to that the lead - zinc bulk concentrate and qualified zinc concentrate are obtained. Then new - type oxide mineral sulphidizer EMS - 3 is adopted to sulphidize oxide lead minerals and oxide lead concentrate is obtained after flotation. By adopting this kind of technological flowsheet the associated silver of the concentrate is enriched and the utilization of mineral resources is maximized.
