摘要
为高效开发利用辽宁某钼矿石资源,在工艺矿物学研究的基础上,对该矿石进行了选矿试验研究。结果表明,该资源为嵌布粒度微细的辉钼矿矿石资源,钼品位为0.217%,有综合回收价值的元素硫主要以黄铁矿和磁黄铁矿的形式存在;磨矿细度为-200目占67%的矿石经2粗2扫浮钼,钼粗精矿再磨至-400目占92.10%后经6次钼精选,钼扫选尾矿1粗1扫2精选硫,中矿顺序返回流程处理,最终获得了钼品位为49.43%、回收率为91.11%的钼精矿,硫品位为53.00%、回收率为73.03%的硫精矿,钼、硫回收指标理想,因此,试验确定的闭路试验流程是该矿石开发利用的合理工艺流程。
Beneficiation experiment is carried out on a molybdenum ore in Liaoning province based on the process miner- alogy research at the aim of high efficiently developing the molybdenum resources. The results show that, molybdenite granular is fine imbedded in the ore with molybdenum grade of 0.217%, and the valuable elements mainly exist in form of pyrite and magnetite. Molybdenum flotation of two roughing-two scavenging is carried out after grinding at the fineness of 67% - 200 mesh. Molybdenum rough concentrate is reground at the fineness of 92. 10% - 400 mesh, and then molybdenum concentrate with molybdenum grade of 49.43% and recovery of 91.11%, and sulfur concentrate with sulfur grade of 53.00% and recovery of 73.03% are received separately through six molybdenum cleaning, and sulfur concentration from flotation tailings of molyb- denum scavenging by one roughing-two cleaning-one scavenging, and middles back to the flowsheet. Both molybdenum and sul- fur is ideally recovered, so this closed circuit process is reasonable for development and utilization of the ore.
