A X-ray fluorescence method is described for determining the major, minor and some trace components (15 elements) in phosphate ore, using both methods of specimen preparation, namely, fusion glass discs and powder-pressed pellets. Concentrations of MgO, Al_2O_3, SiO_2, P_2O_3, K_2O, CaO, TiO_2, MnO and Fe_2O_3 are determined on lithium tetraborate glass discs and F, Na_2O,Cl,Sr,Y and I are determined on powder-pressed pellets into an Al-cup. Matrix correction was performed by theoretical α-coefficients for the major-elements and by the intensity ratio of peak/background(RhKα-Compton) for Sr, Y and I. A full-automatic X-ray spectrometer with an end-window Rh-target X-ray tube is utilized here. The detection limit of F is 0.25% and 0.01% in the case of using a 6μ and 1μ window of proportional counter respectively. Precisions of the method are less than 1% (RSD) for the major-elements. As compared with values of standard and reference samples, the results are satisfactory.
