| 摘 要： | 江西某重选钨尾矿含SiO281.14％、含钼0.022％,钼矿物以辉钼矿为主要,且嵌布特征简单,具有较高的综合回收价值.为了兼顾尾矿作为水泥原料外销的现状,以尽量确保尾矿粒度不明显下降为原则,对试样进行了选钼工艺技术条件研究.试验结果表明,采用两段阶段磨矿、1粗1扫4精l精扫、中矿顺序返回浮选流程处理该试样,最终获得了钼品位为46.520％、回收率为50.95％的钼精矿.

| Abstract: | Tungsten tailings by gravity in Jiangxi contain SiO2 of 81.14% and molybdenum of 0.022%. Molybdenum mineral mainly occurs in molybdenite with features of medium disseminated granularity-simple dissemination and higher recovery value. In order to ensure the export of tailings as cement raw material, it is the principle to ensure the tailings particle size not dropped significantly in the test, and technical conditions of molybdenum concentration are studied. The tests results showed that molybdenum concentrate with Mo grade of 46.520% and Mo recovery rate of 50.95% are finally obtained by the process of two-stage grinding-one roughing-one scavenging-four cleaning-one scavenging for concentrate and middles back to the flow-sheet in turn. |
