Abstract

PURPOSE: To enhance the separation efficiency by using a specified cation exchanger and regulating the shifting rate of an adsorption zone for rare earth elements when rare earth elements are separated from a mixed soln. thereof using a complexing agent and a cation exchanger.
CONSTITUTION: When a soln. contg. a plurality of rare earth elements obtd. from monazite, etc. is separated using a granular cation exchanger, a developing tower provided with a jacket is packed with a cation exchanger having 30W180μm average grain size and 22W80 crosslinking degree. An acceptor soln. is supplied to convert the exchanger into an acceptor type one, and by feeding an adsorbing soln. contg. a mixture of rare earth elements and a complexing agent, an adsorption zone for rare earth elements is formed. A soln. contg. a complexing agent is then fed to shift the zone at 5W500m/day rate. A soln. flowing out of the lower part of the tower is taken out fractionally, and the rare earth elements are recovered separately.
