    Rare Earth and Phosphorus Leaching from a Flotation

    It is well known that there are also some rare earth elements (REEs) which coexist in phosphate rock. Most of them are present in the form of isomorphous substitutions for Ca 2+ as REE-francolite, and a small amount of REEs is hosted in monazite ((Ce,La,Nd,Th)PO 4), xenotime (YPO 4), etc. [3,4].In the wet-process, these REEs are also leached out with the decomposition of phosphate minerals and
