RE-Nb-Fe complex ore in Bayan Obo of North China is a rare multimetallic mine that has 59.3% of the worlds rare earth (RE) reserves and 5.5% of the worlds niobium (Nb) reserves besides abundant iron reserves (Humphries, 2010).However, large quantities of RE and Nb tailings have been discarded during the processing of Bayan Obo ore, resulting in a low utilization ratio (10%) of the RE and even resulting in a complete waste of the Nb.Therefore, it is economically valuable and strategically significant to optimize the recovery of valuable metal resources from Bayan Obo tailings.
