• Abstract: 本实验进行了低品位辉钼矿（8.37%）生产钼酸铵成品的纯度溶解试验、 氯化物、硫化盐分析、及电感耦合离子体 - 质谱（ICP-MS）法对 P、Ca、Fe、 Na、Cu、Pb 含量的测定。实验结果表明：钼酸铵成品最佳纯度为 93.83%，钼总 的回收率是83.55%。实验结果表明：此样品不溶于水，含有氯化物，不含有硫酸盐， Na=0.40 mg/g，Cu=8.57×10 -3 mg/g，Pb=0.81×10 -3 mg/g，不含有 Ca、Mg。
• The experiment has studied on ammonium molybdate produced by low level of molybdenum ore(8.37 %). Firstly, test the purity of ammonium molybdate and analysis resolvable, sulfate, chloride and P, Na, Cu, Pb by inductively coupled plasma- mass Spectrometry. Result was that the best purity of ammonium molybdate was93.83 %. The recyclin g rate of Mo is totally83.55 %. This sample was not dissolved in the water. It does not contain Ca, Fe, sulfate, containin g chloride and P was0.038 mg/g, Na is0.40 mg/g, Cu was8.57×10 -3 mg/g, Pb was0.81×10 -3 mg/g.
