The purpose of the dataset is to further identify patterns and construct maps of the distribution of the contents of the studied components in the tailings storage facility.The chemical composition of the enrichment tailings was determined by an energy-dispersive X-ray fluorescence spectrometer with polarization and monochromatic excitation Rigaku NEX CG II.48.209561, 30.052952NAS of Ukraine
