The application of X-ray fluorescence method in the detection of iron ore since 90s in the 20th century was presented in the text, inclusive of the basic two analysis manners of powder method and fusion method. The main contents were concentrated on the testing technology of iron ore analysis with fuse-wavelength dispersive X-ray fluorescence spectrometry, with focus on the presentations of the application of the type of flux, mixture ratio, fusion method, melting temperature and cobalt internal standard.xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
