FOERFARANDE FOER AOTERVINNING AV UR FOSFATLOESNINGAR EXTRAHERAT URAN I FORM AV FYRVAERD FLUORID.

摘要

Uranium is recovered as UF4 from phosphate solutions. The uranium is reduced to the tetravalent state and extracted with an organic extractant. The uranium is recovered as UF4 by reextracting with an aqueous HF solution which includes UF4 in suspension for improved reextraction.
