An extraction chromatographic method fo: rapid separation of Ce- and Y-group of rare earth in ores using HDEHP resin has been studied. The Ce- group was separated quantitatively from Y-group by elution with 50 ml of 0.4 N hydrochloric acid and the Y-group was eluted quantitatively with 50 ml of 4 N hydrochloric acid. Each component can be determined by direct photometric method.
