Abstract
A process is disclosed for recovering scandium from impure scandium bearing material. The process involves contacting a solution of scandium which contains impurities, with a solvent impregnated resin consisting essentially of a solid polymeric medium in which is dispersed a liquid alkyl phosphoric acid as a cation extracting agent to extract essentially all of the scandium by the extracting agent without extracting appreciable amounts of impurities, and removing the scandium from the resin.
