Progress on X-ray fluorescence spectrometry for iron ore analysis
In this paper,the literatures on iron ore analysis by X-ray fluorescence spectrometry(XRF)pub-lished in China since 2011 were reviewed.The preparation conditions of test portion piece,test portion for calibration curve used,the analysis conditions of instrument,the evaluation of calibration curve,the eval-uation of analysis system,the evaluation of measurement uncertainty and related applications of pressed powder pellet and fusion sample preparation are summarized.The application prospect of XRF in compo-nent analysis of iron ores was prospected.It was suggested to conduct the research and application on test portion pieces for calibration curve and test portion pieces for standardization for primary and secondary components analysis of iron ore by XRF.Moreover,the application of high-pressure powder pelleting preparation technique in XRF analysis of iron ore was also proposed.
