Besides existing as independent rare earth minerals, these elements are commonly found in association with phosphate ores[15], [9], [41], [48]. Therefore phosphate ore has become an essential alternative source for REEs extraction [16], [9], [7], [12]. However, it faces the main problem of difficult separation and recovery of phosphorus and REEs.
