A new method has been developed for the determination of 14 components including WO3, Mn, Fe, CaO, SiO2, Sn, Mo, Cu, Bi, Pb, Sb, Zn, Cd and Cr in tungsten concentrates by wavelength-dispersive X-ray fluorescence spectrometry. The samples were fused with mixture flux of synthesized with high purity compounds. The common background method was used for background calibration and the variable theoretical α-coefficient method was used for matrix effect calibration. The method provides the advantages of high accuracy, high precision, high efficiency and has been applied to the routine analysis of tungsten concentrates.
