摘要: 针对黑龙江某大型斑岩型钼矿生产的钼精矿铜、铅杂质超标的问题,在完成矿石性质研究基础上,开展 了选矿工艺优化研究。结果表明,对含钼0. 122%的原矿,采用自主研发的钼高效捕收剂PM 和粗磨—钼分步浮选— 钼铜混合浮选—钼铜粗精矿再磨—铜钼分离工艺流程处理,全流程闭路试验取得了钼品位54. 32%、钼回收率 90. 69%、杂质铜含量0. 048%、铅含量0. 062%的较好钼精矿指标。相较于原工艺流程,新工艺得到的钼精矿铜含量降 低了0. 322 个百分点、铅含量降低了0. 348 个百分点。优化工艺有效地降低了钼精矿中铜、铅杂质含量,研究结果可 为该矿石的开发利用提供依据。

Abstract: Aiming at the problem of excessive copper and lead content in molybdenum concentrate of a large porphyry molybdenum mine in Heilongjiang,the beneficiation optimization test was conducted based on the process mineralogy. The test result showed that the molybdenum concentrate assaying Mo of 54. 32%,Mo recovery rate of 90. 69%,Cu of 0. 048%,Pb of 0. 062% was obtained by using flowsheet of coarse grinding,Mo step flotation,Mo-Cu bulk flotation,Mo-Cu bulk concentrate regrinding and separation of Cu-Mo combined with the self-developed effective molybdenum collector PM for the ores assaying Mo of 0. 122%. Compared to the original process,the copper content in the molybdenum concentrate obtained by the new process had been decreased by 0. 322 percentage points and the lead content had been decreased by 0. 348 percentage points. The process successfully reduced the impurity content of copper and lead in molybdenum concentrate. The research results can provide a basis for the development and utilization of the ore.
