摘　　要：内蒙古某铅锌金矿属于非常复杂难选的铅锌金多金属矿床,原来的选矿流程的生产指标不能达标,通过采取去掉旧流程中螺旋溜槽的粗、精、扫选,将旧流程"先浮硫化矿再浮氧化矿"的原则流程改为"铅锌硫化矿和氧化矿同步浮选"等措施,简化了铅锌浮选流程,缩短了选别时间.对金银的回收,采取对槽体铺设毛毡等措施,大幅度提高了金银的选别指标.锌精矿品位从原来不达标的35.00%提高至51.25%;锌精矿锌回收率从原来51.18%提高到75.17%;铅精矿品位从41.10%提高到53.37%,铅回收率提高了4.33%.同时,金银得到有效回收,回收率达到80.00%.本次对旧流程的改造很成功,为企业创造了巨大的经济效益.One of the lead-zinc mine in Inner Mongolia is a lead-zinc-gold polymetallic deposit.The original production process indexes cannot meet the production requirements.The transformation process put off the roughing,clearing and scavenging process and changed the process of＂sulfide ore flotation before oxide ore flotation＂into＂synchronization flotation of sulfide and oxide ore＂.The transformation process not only can simplify the flotation process,but also shorten the dressing time.In terms of the recovery of gold and silver,the new process improves the indexes of gold and silver obviously.The grade of zinc concentration improves from 35.00%to 51.25%,the recovery of zinc improves from 51.18% to 75.17%.The grade of lead concentration improves from 41.10%to 53.37%.The recovery of lead improved 4.33 percentage.At the same time,the gold and silver recovered efficiently and the recovery reached 80.00%.The practical transformation on the current process successfully created a huge economic benefits for the enterprise.
