摘要:
兰坪铅锌矿是国内储量最大的铅锌矿,其中氧化铅锌矿占了一半左右,兰坪氧化铅锌矿的选矿是国内外公认的难题.针对兰坪氧化铅锌矿,项目组进行了大量的试验研究.通过一系列设计、复配、合成,研发了新型氧化铅锌矿捕收剂KZ,并取得了较好的试验技术经济指标,在最佳分选条件下,最终闭路试验硫化铅精矿Pb 50.60%、铅回收率21.82%,氧化铅精矿Pb 49.96%、铅回收率22.57%,总铅精矿Pb 50.27%、回收率44.39%.硫化锌精矿Zn 47.25%、锌回收率25.84%,氧化锌精矿Zn 31.83%、锌回收率60.92%,总锌精矿Zn35.25%、回收率86.76%的技术经济指标,达到了国内先进水平.
Abstract:
Lanping's lead-zinc ore is the largest domestic lead-zinc ore,including oxide lead-zinc deposit account for about half,Lanping's oxide lead-zinc ore dressing is a difficulty problem at home and abroad.In this project,we carried out a large number of experimental research.After a lot of design and compositions study,a new zinc oxide ore collector named KZ was successfully developed.The locked-cycle test obtained lead sulfide concentrate with the lead of 50.60% and recovery of 21.82%,oxide lead concentrate with the lead of 49.96% and recovery of 22.57%,the total lead concentrate with the lead of 50.27% and recovery of 44.39%,zinc sulfide concentrate with the lead of 47.25% and recovery of 25.84%,oxide zinc concentrate with the lead of 31.83% and recovery of 60.92%,the total zinc concentrate with the zinc of 35.26% and recovery of 86.76%,which reached the domestic advanced level.
