摘要
某钼、钨多金属矿石,有用矿物主要有辉钼矿、黄铁矿和黑钨矿。根据其矿石性质,对钼浮选过程中脉石矿物抑制机理进行了分析,提出"依次浮选-强磁选"的工艺流程,获得了钼精矿品位45.33%、回收率80.49%,硫精矿品位45.83%、回收率92.74%,钨精矿品位58.67%、回收率74.63%的良好指标。
Molybdenite, pyrite and wolframite are associated in a Mo-W Polymetallic Ore. The suppressive mechanism of gangue mineral has been analyzed for the molybdenum flotation process based on the mineralization characteristics. The technology process combining suocessive floatation with high-gradient magnetic separation was applied resulting the following favorable processing targets： molybdenum concentrate grade 45.33 %, recovery rate 80.49 %; sulfur concentrate grade 45.83 %, recovery rate 92.74 %; tungsten concentrate grade 58.67 %, recovery rate 74.63 %.
