Abstract:
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.
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。
