Extraction of lanthanons with alkali metal amalgams. II. A counter-current process for the extraction of samarium or ytterbium

Autor: M. F. Barrett, N. E. Topp

Publikováno v: Journal of Applied Chemistry. 13:7-12

A technique is described for the continuous extraction of samarium or ytterbium from rare earth concentrates. Extraction is carried out in a packed column by passing a solution of a lanthanon concentrate countercurrent to a dilute sodium amalgam. A s
