Improvement to the PbMoO₄ Weight Method by Increasing the Content of Molybdenum (Mo) in the Molybdenum Ore Abstraction

By using the strong acid resolution, such as the hydrochloric acid (HCl) and the nitric acid (HNO₃), relating with molybdic acid radical (MoO₄) to produce precipitates of the molybdate precipitates, and reacting with (CH₃COO)₂Pb to produce the precipitates of tungstenic acid (WO₄), the arsenic acid radical (AsO₄), the phosphoric acid radical (PO₄), the vanadic acid radical (VO₃), the chromic acid radical (CrO₄) and so on. By means of the controlling of the acidity, the medium, the precipitation condition, with lead acetate Pb (CH₃COO)₂ precipitations methods, mensurating the content of molybdenum (Mo) in the molybdenum ore, we obtain the good analysis result.
