摘要
A method for separating substantially pure rare earth metals and other metals from a mixed source, including putting a plurality of rare earth metals and other metals into solution to define a solution containing a plurality of respective metal ions, in at least one chromatographic column, selectively capturing ions of each respective metal with a respective ligand to define a plurality of respective discrete bands, and respectively eluting captured ions of respective metal from each respective band of the at least one chromatographic column to yield a plurality of purified solutions, each respective purified solution having a high concentration of a respective metal. The bands may either be stationary with respect to the columns, or may move through the columns.
