Literature review on application of X-ray fluorescence spectrometry in analysis of iron ores

The literatures on application of X-ray fluorescence spectrometry (XRF) in analysis of iron ores, which were published since 1970s in China, were reviewed. Among total 101 literatures, 78 of them were about fusion sample preparation, 11 of them were about pressed powder pellet and 12 of them were about energy dispersive instrument analysis and field application. The basic conditions for the analysis of iron ores were firstly introduced, including monographs, certified reference materials, standard methods and comprehensive review papers. Then the main points of literatures were introduced in the form of table. The fusion method, the pressed powder pellet method and the energy dispersion method for the analysis of multi-elements were focused on. Finally, the practical problems in the analysis of iron ores were discussed, including the granularity effect, the mineral effect, the selection of sample preparation method and the application of internal standard. Some important issues in the analysis of iron ores by XRF were discussed. Moreover, the development prospect of XRF in the analysis of iron ores was also predicted. It indicated that XRF had become one of most convenient analysis methods in analysis of major and minor elements in iron ores. Total 151 papers were cited.
