提高某复杂铅锌多金属矿回收率的工艺研究及生产实践

Process Research and Production Practice for Improving the Recovery Rate of a Complex Lead-zinc Polymetallic Ore

针对某结构复杂、粒度不均、氧化程度高的铅锌矿,通过优化铅锌矿浮选流程和药剂制度,解决复杂铅锌矿回收率低问题。主要通过阶段磨矿、分步快选、氧硫混选和联合给药等来提高复杂铅锌矿回收率。

For lead-zinc ore with complex structure,uneven size and high degree of oxidation,by optimizing lead-zinc flotation process and reagent system,low recovery rate of complex lead-zinc ores can be solved. The recovery rate of complex Pb-Zn ore is improved by stage grinding,step-by-step rapid separation,oxygen-sulfur mixture and combined administration.
