Methods of chromatographic separation of Cu, Fe and Zn using AG MP-1 anion exchange resin developed previously were focused mainly on the purification of ordinary geological materials. It is unclear whether those methods are suitable for separation of some special geological materials such as Bayan Obo ore samples which show extreme enrichment of REE and Nb. The results show that the method established before can make effective separation of REE and W with Fe, and that nearly 90% of Nb and Ta can be washed out before Fe elution using 6 mol/L HCl. The behaviors of Fe, Co and Cu observed in the investigation are consistent with previous studies.
