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.
