摘要:
针对青海某铜铅锌多金属矿，进行了不同类型捕收剂对铜铅锌浮选分离影响的试验，重点考察了新型捕收剂4037B、P5100C、QBSC的选别效果。结果表明：P5100C和QBSC更有利于铜、铅分离，在最佳条件下，采用铜快速浮选—铜铅混选—铜铅再磨分离—锌浮选流程，获得铜品位35.56 %、铜回收率75.23 %的铜精矿；铅品位45.02 %、铅回收率71.92 %的铅精矿；锌品位41.49 %、锌回收率72.58 %的锌精矿；含铜20.14 %、含铅8.90 %、含锌28.38 %，铜回收率11.93 %、铅回收率6.77 %、锌回收率11.81 %的混合精矿。全流程铜总回收率97.94 %，铅总回收率96.62 %，锌总回收率92.64 %。

Abstract:
This study investigates the effects of different types of collectors on the flotation separation of copper,lead,and zinc in a polymetallic mine in Qinghai.The emphasis was placed on evaluating the separation efficiency of new types of collectors 4037B,P5100C,and QBSC.The results indicate that P5100C and QBSC are particularly effective for the separation of copper and lead.Under optimal conditions,a process comprising rapid flotation of copper-mixed flotation of copper and lead-regrinding and separation of copper and lead-zinc flotation,yielded a copper concentrate with a grade of 35.56 % and a recovery rate of 75.23 %,a lead concentrate with a grade of 45.02 % and a recovery rate of 71.92 %,and a zinc concentrate with a grade of 41.49 % and a recovery rate of 72.58 %.A mixed concentrate was also obtained with copper grades of 20.14 %,lead grades of 8.90 %,zinc grades of 28.38 %,and recovery rates of 11.93 %,6.77 %,and 11.81 % for copper,lead,and zinc,respectively.The overall copper,lead,and zinc recovery rates were 97.94 %,96.62 %,and 92.64 %,respectively.
