Abstract: A fast and simple approach to directly determine SiO₂、Al₂O₃、Fe、MgO、CaO、K₂O、Mn、TiO₂、P and Zn in manganese ores samples by X-ray fluorescence spectrometer(XRF)was developed. This method used a glass fuse piece technique with Li₂B₄O₇、LiBO₂ and LiF (Mass ratio:45:10:5) as the flux, NH₄NO₃ as the oxidant, LiBr as the stripping agent. Several experimental parameters were optimized, and the analytical figures of merit were evaluated. The components in the certified reference material of GBW07261~GBW07266 were determined by the proposed method. The relative standard deviation (RSD, n=12) was less than 2%. The accuracy test was conducted with synthetic samples. The results were consistent with the certified values.
