FIELD: chemistry.
SUBSTANCE: use: for separate determination of content of tungsten and molybdenum in complex ores. Summary of invention consists in the fact that irradiating walls of the well with primary radiation while simultaneously detecting secondary radiation induced by atoms of the determined elements, wherein primary radiation is represented by neutron radiation from a stationary source, and gamma-radiation of inelastic scattering of neutrons on nuclei of atoms of determined elements is induced by gamma-spectrometer, one channel of which is tuned to energy of gamma-radiation of inelastic scattering of tungsten neutrons, and the other - to energy of similar gamma-radiation of molybdenum.
EFFECT: technical result is increased representation and reliability of results of determination of content of tungsten and molybdenum in ores of complex composition.
