摘　　要：某低品位铅钼粗精矿中（含钼4.39%）钼主要以钼酸铅矿物形式存在,采用硫化钠浸出工艺提取氧化钼。在粒度-74μm占83%、硫化钠用量为理论量的2.5倍、液固比3∶1、浸出温度90~95℃、浸出时间1 h的条件下,钼浸出率85%,铅以硫化铅形式进入浸出渣,实现了钼酸铅矿中钼铅的分离。The molybdenum in lead concentrate（Mo content of 4.39%） mainly existed in forms of PbMO4.The sodium sulfide leaching process was adopted for oxidation molybdenum extraction.The leaching rate of molybdenum was 85% under the conditions that particle size of ore was 83%-0.0074 mm,the dosage of sodium sulfide was two times as the theoretical value,the ratio of liquid（volume） to solid（mass） was 3∶1,the leaching temperature was 90~95 ℃ and the leaching lasted 1 h.So,Lead was remained in the leaching slag in the form of lead sulfide,and the separation of lead and molybdenum was achieved.
