Abstract：After sample was dried at 110 ℃, calcined at 700 ℃, mixed flux (mLiB2O4∶ mLiBO2∶ mLiF = 4.5∶1∶0.4) and sample were diluted to 30∶1, before 2 g of NH4NO3 was added as the oxidant, and lithium bromide solution was added as the release agent. The resulting mixture was fused for sample preparation. The matrix effect was corrected with Compton scattering internal standard method together with the experiential coefficient method, and thus the quantitative analytical method for the determination of 15 components including Pb, Zn, Cu, SiO2, Al2O3, TFe2O3, TiO2, MnO, CaO, MgO, K2O, Na2O, Sb, Bi and Ag in lead-zinc ore by X-ray fluorescence spectrometry was established. The method was applied to the analysis of the national lead-zinc certified reference material GBW07163, with the relative standard deviation for each component of 0.29%-7.1 %. And the analysis of national lead-zinc ore certified reference materials GBW07165 and GBW07173 that did not participate in regression testing rendered results consistent with the certified values, so it could fully meet the require of daily production.
