The Inductively Coupled Plasma-mass Spectrometer (ICP-MS) was used for measuring the content of rare earth elements in Guizhou high-sulfur and high-silicon bauxite ore and products of mineral processing. The results show that the rare earth elements are mainly enriched in the aluminum concentrate, but the content in sulfur concentrate is reduced, which shows that during desulfurization of high-sulfur and high-silicon bauxite by mineral processing, the associated rare earth element in aluminum concentrate, especially the light rare earths are also enriched.
