Various liquid-liquid extraction systems for the separation of yttrium and the rare earths are described. These laboratory single extractions (shake- outs) were conducted to determine which solvent extraction mechanisms should be considered for trial on a larger scale. The best separation of yttrium and the heavy rare earths from the light rare earths was accomplished with a monododecyl phosphoric acid in solutions of kerosene and n-decanol using scrub solutions of hydroxyethylethylenediaminetriacetic acid with the pH at 4.0 to 5.0. Thus far no other extracting agents investigated have given separation factors comparable to those obtained with the phorphoric acid reagent under the particular conditions used in these experiments.
