Recovery and Separation of Rare Earth Elements Using ...

 · Recycling rare earth elements REEs used in advanced materials such as Nd magnets is important for the efficient use of REE resources when the supply of several REEs is limited. In this work, the feasibility of using salmon milt for REE recovery and was examined, along with the identification of the binding site of REEs in salmon milt.
