Determination method of scattered precious trace metal rhenium in molybdenite concentrate

The invention relates to a method for determining rare and dispersed precious trace metal rhenium in molybdenite concentrate, which specifically comprises the following steps: dissolving a sample in a nitric acid-hydrogen peroxide strong oxidation system, oxidizing rhenium to form faint yellow stable Re2O7, forming MoO3 precipitate by Mo, dissolving Re2O7 in water to generate soluble and stable perrhenic acid, not dissolving MoO3 precipitate in water, separating Mo from Re by filtering, and determining the content of rhenium in the molybdenite concentrate. And eliminating matrix interference of molybdenum, determining the filtrate by adopting an ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry) method, and calculating the content of rhenium. The simple, convenient, accurate and rapid method for measuring the rare and dispersed precious rhenium element in the molybdenite concentrate is established, the accuracy of measuring the trace rhenium element is improved, the defect problem of measuring
