| 摘 要： | 针对某含泥高银铅锌硫化矿，在低碱环境下采用25号黑药与苯胺黑药组合捕收铅，有效兼顾了贵金属银的回收，锌浮选采用石灰和8372CN组合抑硫，缓解了矿泥对锌精矿品质的影响。闭路试验获得了铅品位67.18%、铅回收率94.57%、银品位2 560.37 g/t、银回收率80.54%、锌含量3.60%的铅精矿和锌品位51.63%、锌回收率93.27%的锌精矿，实现了含泥高银铅锌硫化矿的高效综合利用。

| Abstract: | In processing a mud-bearing high-silver lead-zinc sulfide ore, collectors of dimethylphenyl dithiophosphate and aniline aerofloat were used in combination to collect lead minerals in a low alkali environment, while the noble metal of silver was comprehensively recovered. Furthermore, lime combined with 8372CN were used to depress pyrite in zinc flotation process, thus alleviating the influence of sludge on the quality of zinc concentrate. The closed-circuit flotation test yielded a lead concentrate grading 67.18% Pb at 94.57% recovery, 2 560.37 g/t Ag at 80.54% recovery and 3.60% Zn, and a zinc concentrate grading 51.63% Zn at 93.27% recovery. With this flowsheet, an efficient comprehensive utilization of a mud-bearing high-silver lead-zinc sulfide ore can be actualized. |
