This paper reported a method for the determination of major and minor components(WO_3,Fe_2O_3,MnO_2,CaO,SiO_2)in tungsten concentrate by X-ray fluorescence spectrometry with fusion sample preparation.The granular effect and mineral effect of sample were eliminated through fusion sample preparation.D.Jongh mathematical model was introduced to correct spectral line interference and the sample matrix effect.The relative standard deviations were in the range of 0.154%-1.900%.Three actual samples were tested to ...
