摘　　要：某混合钼矿氧化率为11.46%,脉石矿物易泥化,同时含有铜、铅、锌等多种金属元素,属于难选混合钼矿。针对该钼矿的矿石性质,研究采用阶段磨选,一粗-两扫-粗精矿再磨-十精的工艺流程,获得品位为45.47%,回收率为80.19%的钼精矿,达到了KMo45-A级钼精矿标准。研究成果对类似矿石的开发利用有一定的参考意义。One kind of refractory mixed molybdenum,with oxidation rate of 11. 46% and easily mudding gangue minerals,contains copper,lead,zinc,and other metal elements. According to the property of the molybdenum ore,stage grinding was selected with the process of one roughing,two cleaning,molybdenum crude concentrate regrinding and ten scavenging. As a result,a molybdenum concentrate with grade of 45. 47% and recovery of 80. 19% was obtained,which reached KMo45-A grade molybdenum concentrate standard. This study has certain reference value for the utilization of similar ores.
