Abstract

A method for identifying and separating a rare earth ion. The method includes bringing one or more rare earth ions into contact with a mineralization agent capable of mineralizing the rare earth ions, wherein the one or more rare earth ions are separated as rare earth minerals, based on a mineralization tendency of the mineralization agent with respect to a rare earth ion series.
