| 摘 要： | 陕西某含铅硫化钼矿石中的钼铅矿物以原生硫化物为主，共生关系密切、嵌布粒度细微，对该矿石进行了选矿工艺技术条件研究。结果表明，采用一段磨矿、1粗1扫钼铅混浮、钼铅混合粗精矿再磨、3次混合精选、1粗2扫2精钼铅分离、中矿顺序返回流程处理该矿石，最终获得了钼品位为52.32%、回收率为92.50%、含铅4.52%的钼精矿和铅品位为40.98%、回收率为70.42%、含钼0.43%的铅精矿。

| Abstract: | The Mo-Pb minerals in a molybdenum sulfide ore containing lead in Shaanxi are mainly the native sulfides which are closely associated with each other and have fine dissemination. Technical condition tests for beneficiation of the ore were studied. The results showed that through the process of one stage grinding-mixed flotation with one roughing and one scavenging,regrinding of mixed Mo-Pb coarse concentrate,three stage mixed cleanings，Mo-Pb separation with one roughing，two scavenging and two cleanings,middles back to the flowsheet in turn，molybdenum concentrate with Mo grade of 52.32%，recovery of 92.50% and Pb content of 4.52%，and Lead concentrate with Pb grade of 40.98%，recovery of 70.42%，and Mo content of 0.43% were finally obtained. |
