Separating Rare Earth Elements. As alluded to earlier, the rare earth elements are so similar in physical and chemical properties that it is extremely difficult to isolate and purify them. Historically, chemists have chosen the difficult procedure of fractional crystallization for the task. It sounds like it should be easy enough.
