低品位钼矿制备钼酸铵的成品分析

Research on the Analysis of Anmonium Molybdate by Low Level of Molybdenum Ore

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=8.57×10-3mg/g,Pb=0.81×10-3mg/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 was 93.83 %.The recyclin g rate of Mo is totally 83.55 %.This sample was not dissolved in the water.It does not contain Ca,Fe,sulfate,containin g chloride and P was 0.038 mg/g,Na is 0.40 mg/g,Cu was 8.57×10-3 mg/g,Pb was 0.81×10-3 mg/g.
