Abstract: Detailed analysis is made on the origin of the uncertainty in impurity element determination with the case of SiO2 measurement for sintered iron ore by X-ray fluorescent spectrometry (XRF). The uncertainty of the measurement results is assessed. This method is also suitable for the assessment of the uncertainty of XEF determination for other impurity elements in iron ore.

Key words: XRF method, SiO2, Uncertainty
