Abstract：Copper sulfide ore and its concentrate contain high content of sulfur and copper. The X-ray spectral lines (Kα and Kβ) of sulfur with different valence states will drift, leading to the inconsistent spectral intensity ratio (Kα/Kβ). Moreover, sulfur can corrode the platinum-gold crucible, and copper can react with platinum to form alloy. These problems bring difficulties for the X-ray fluorescence spectrometric (XRF) analysis. The domestic reports on determination of copper sulfide ore and its concentrate by XRF are reviewed. The sample preparation conditions by powder pressed pellet and fusion sample preparation methods, the selection of standard sample, the XRF analysis conditions as well as the application in isomorphism phase identification of copper ores, oxidation conditions and mechanism of copper concentrate are summarized. The application of XRF method in analysis of copper sulfide ore and its concentrate is prospected.
