Abstract

PURPOSE: To enhance the separation efficiency by regulating the sphericity, average grain size and grain size distribution of a granular cation exchanger when rare earth elements are separated from a mixed soln. thereof using a complexing agent and the cation exchanger.
CONSTITUTION: When a soln. contg. a plurality of rare earth elements obtd. from monazite, etc. is separated into the elements using a granular cation exchanger, a developing tower provided with a jacket is packed with a cation exchanger having 30W180μm average grain size and a grain size distribution in which ≥80% of the exchanger exists in the range of 0.7W1.4 times as large as the average grain size, and ≥95% of the exchanger has ≤2.0 roundness. An acceptor soln. is added 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 by displacement development. A soln. flowing out of the lower part of the tower is taken out fractionally, and the rare earth elements are recovered separately.
