Using solution technique, sulfur in the sulfide ore was indirectly determined by X-ray fluorescence spectrometry. The sample was dissolved with the mixed solution of Br2 and HNO3, and SiO2, a major constituent, was repelled from the solution by HF treatment several times, Ba2+ solution was added to the solution to precipitate the SO42- ion as BaSO4. Measuring the fluorescent X-ray intensity of excess Ba2+ ion in the filtrate, the content of sulfur in the original ore was back-calculated. Comparing the results by this method with the gravimetric method, the mean difference was ±1.7% in the range of 20 to 40% of sulfur content and the method was tolerably reproducible.
