| 摘 要： | 内蒙古某低品位微细粒嵌布的难选铅锌硫化矿石铅品位为1.47%、锌品位为1.93%,为了确定该矿石的开发利用工艺,在进行系统工艺矿物学研究的基础上进行了铅锌浮选试验。结果表明:①矿石中的铅、锌均主要以硫化物相形式存在,主要金属矿物为铁闪锌矿、方铅矿,磁黄铁矿和黄铁矿含量较高;方铅矿与铁闪锌矿间以及与其他矿物间的共生关系密切,方铅矿呈中-微粒嵌布,粒度主要为0.64~0.01 mm,铁闪锌矿呈细-微粒嵌布,粒度主要为0.16~0.01 mm。②矿石在磨矿细度为-0.074 mm占80%情况下采用1粗4精3扫流程选铅,选铅尾矿1粗4扫选锌,锌粗精矿再磨至-0.025 mm占90%情况下经4次精选,最终获得铅品位为52.23%、含锌3.18%、铅回收率为74.81%的铅精矿,锌品位为42.05%、含铅1.98%、锌回收率为85.83%的锌精矿,较好地实现了铅锌的分离与回收。

| Abstract: | A refractory lead-zinc sulfide ores with low grade and fine-grained disseminated in Inner Mongolia contains 1.47% lead and 1.93% zinc. In order to determine the utilization process of the ores， flotation tests of lead and zinc was carried out on the basis of process mineralogy. The results showed that: ① Lead and zinc in the ores are mainly in the form of sulfide phase. The Main metallic minerals in the ores are marmatite and galena， and the contents of pyrrhotite and pyrite are high. Galena ，marmatite and other minerals are coexistent. Galena is disseminated with medium-particles ， mainly between 0.64 mm and 0.01 mm grain size， while marmatite is disseminated with fine-particles， mainly between 0.16 mm and 0.01 mm grain size.② In the case of grinding fineness of 80% -0.074 mm，lead concentrate was obtained through one roughing， four cleaning and three scavenging flotation. Zinc primary concentrate was selected by one roughing four scavenging from lead tailings. After regrinding zinc primary concentrate to 90% -0.025 mm， zinc concentrate was obtained through four cleaning. Lead concentrate with lead grade of 52.23%，zinc grade of 3.18%，lead recovery rate of 74.81% and zinc concentrate with zinc grade of 42.05%，lead grade of 1.98%，zinc recovery rate of 85.83% were finally obtained. The process effectively realized the separation and recovery of lead and zinc. |
