Process for obtaining uranium or uranium compounds from phosphoric acid

Creators

Description

The liquid/liquid extraction is done using amines, dissolved in organic solvents insoluble in water in the presence of complexers. Alkyl amine combined with polyphosphate and/or meta phosphate ions has proved an excellent reagent in the presence of FeII ions. The extraction is preferably done in the range of concentrations of 0.7% to 57% P2O5. (DG)

Abstract (German)

Die Fluessig/Fluessig-Extraktion erfolgt mit Hilfe von Aminen, geloest in wasserunloeslichen organischen Loesungsmitteln in Gegenwart von Komplexbildnern. Als hervorragendes Reagenz hat sich Alkylamin in Verbindung mit Polyphosphat- und/oder Metaphosphationen und in Gegenwart von FEII-Ionen erwiesen. Die Extraktion erfolgt vorzugsweise im Konzentrationsbereich von 0,7% bis 57% P2O5. (DG)
