摘　　要：根据保山隆阳金铅锌氧化矿矿石性质特点,进行了单一和联合的选矿工艺研究,结果表明,采用"原矿氰化浸出—磁选除铁—摇床重选"的工艺流程,金的回收率可达83.3%,铅精矿指标为含铅53.05%,铅回收率20.17%,锌精矿含锌15.86%,锌回收率为24.24%。The single and joint ore processing technology study is carried out according to the ore properties of Baoshan Longyang gold-lead-zinc oxided ore, the results show that the ＂raw ore cyanide leaching-magnetic separation iron removal-table concentrator gravity separation＂ process flow is adopted, so that the recovery rate of gold can be reach to 83.3%, the lead concentrate target is that the lead- bearing 53.05%, the recovery rate of lead is 20. 17%, the zinc beating rate of lead concentrate is 15. 86%, and the recovery rate of zinc is 24. 24%.
