Abstract
A method for isolating scandium values is provided. The method includes extracting scandium values from a leachate with an organic solvent, thereby obtaining a scandium-loaded organic solvent, wherein the leachate contains iron and scandium ions, and wherein the organic solvent contains a primary amine. The scandium values are then stripped from the scandium-loaded solvent with a stripping solution containing an acid and a salt.
