Abstract

Methods for primary processing of fluorophosphate rare earth concentrate precipitated from phosphoric acid of dihydrate process by introduction of fluoride ion were examined. Separation of rare earth cations from phosphorus, fluorine, and an appreciable part of the impurity cations by interaction of the concentrate with sulfonic cation resin in sulfuric acid was suggested. Further processing of sulfonic cation resin containing rare earth elements was possible by known methods.
