| 摘 要： | 云南某难选铅矿矿石中有用矿物以方铅矿和铅矾为主,氧化率达30%以上,并伴生有黄铁矿。为了给该矿产资源开发利用提供依据,对其进行了选矿试验研究,结果表明,采用优先浮硫化矿—脱泥—再浮氧化矿试验方案,其中硫化矿浮选采用对方铅矿选择性较好的捕收剂GY,氧化铅浮选采用硫化钠进行较长时间的硫化,最终获得了含铅43.56%、铅回收率58.45%的硫化铅精矿和含铅31.26%、铅回收率21.98%的氧化铅精矿,合并铅精矿的品位为39.33%、铅回收率80.44%,达到了选矿厂要求,有效提高了有价元素的回收利用率。

| Abstract: | Some refractory lead ore from Yunnan contains mainly galena and lead sulfate as valuable minerals that are associated with pyrite,and the ore's oxidation rate is more than 30%.Beneficiation tests are made on this ore to provide a basis for its exploitation and utilization.The process consisting of preferential sulfide minerals flotation,desliming and oxide ores flotation in which GY is used as the collector for the sulfide minerals flotation and Na2S is vulcanized for a relatively longer time for oxide ore ... |
