For the first time, the rare earth elements (REE) content of two samples of zircon concentrate from local manufacturers was investigated using instrumental neutron activation analysis (INAA) and energy dispersive X-ray fluorescence analysis. A comparator variant of INAA was used, which divided the elements into three groups based on detector type, radionuclide half-lives, and suitable comparator.
Two samples of zircon concentrate by local manufacturers were investigated for the first time for their rare earth elements (REE) content by instrumental neutron activation analysis (INAA) and energy dispersive X-ray fluorescence analysis. Comparator variant of INAA based on an external standard (Fe) and two internal standards (Th, La) was used to determine the elements divided into three groups depending on the detector type, radionuclide half-lives, and suitable comparator.High Y and heavy REE contents of the samples exceeding their crustal averages up to two orders of magnitude confirmed significance of the zircon concentrate as an important source of these elements production as a by-product.
