摘　　要：广西某钼矿石钼品位较低,金属矿物种类单一,主要为辉钼矿,但嵌布粒度较细。对该矿石进行了选矿工艺技术条件研究。结果表明,粗磨—粗选—粗精矿再磨—精选流程是处理该矿石的高效节能流程,采用1粗2扫6精、中矿顺序返回流程处理该矿石,最终可获得钼品位为49.67%、回收率为92.70%的钼精矿。A molybdenum ore in Guangxi is fine-grained disseminated and low in grade.It′s mainly exists in molybdenite,with single metallic mineral.Technical conditions for beneficiation of the ore were studied.The results showed that the process of rough grinding-rough concentration-regrinding for coarse concentrate-cleaning concentration is an efficient and energy-saving process for treating this type of ore.Molybdenum concentrate with Mo grade of 49.67% and recovery of 92.70% was finally obtained by the process of one roughing,two scavengings,six cleanings and middles back to the process in turn.
