摘要: 在对福建某多金属铜锌硫化矿进行工艺矿物学研究的基础上,按常用的抑锌浮铜原则流程进行了系统的铜、锌分离回收试验。试验研究表明,采用1粗1扫2精浮铜、1粗2扫3精浮锌、中矿顺序返回的工艺流程处理该铜锌多金属硫化矿,可得到铜品位24.23%、铜回收率89.92%、含锌2.02%的铜精矿,以及锌品位53.55%、锌回收率81.87%、含铜1.33%的锌精矿。

Abstract: Based on the process mineralogy research on a polymetallic Cu-Zn sulphide ore,carried out the systemic recovery test of copper and zinc according to the flowsheet of floating Cu and inhibiting Zn.The results indicate that take the process flowsheet of one roughing,one scavenging two a cleaning to float copper, one roughing,two scavenying and three cleaning to float and the middlings ordinal returning for processing the polymetallie sulphide ore.A copper concentrate with grade at 24.23% and recovery at 89.92% and a zinc concentrate with 53.55% grade and 81.87% recovery are obtained.
