A rapid and selective X-Ray fluorescence spectrometric method for deter- urination of trace amounts of REE in ores is described. It is based on the pre- concentration with ion-exchange paper. Beer's law is obeyed for REE of 0-100ppm. The detection limit is 0.x ppm. The results obtained are in good agreement with those obtained by isotopic dilution measurement and neutron activation analysis.
