Abstract: This invention relates to a process for the purification of yttrium which comprises adding ammonium thiocyanate to an impure aqueous solution of yttrium containing as contaminants mainly heavy rare earth elements as impurities, further adding to the resulting mixture, as a solvent, a quaternary ammonium salt containing cyclohexyl radicals, straight chain alkyl radicals and at least one methyl radical but containing no aryl radical, or a composite solvent system consisting of a quaternary ammonium salt and a trialkylphosphine oxide or a triarylphosphine oxide, and extracting the heavy rare earth elements in said aqueous solution into the solvent phase thereby leaving the yttrium in the aqueous phase.
