EXTRACTION OF URANIUM FROM WET-PROCESS PHOSPHORIC ACID

A process for extracting uranium compounds from wet-process phosphoric acid (WPA) includes lowering iron content of WPA to produce a lowered iron WPA, reducing valency of any remaining iron in the lowered iron WPA to produce a reduced iron valency WPA. Uranium compounds are extracted from the reduce...

Beschreibung
Zusammenfassung:	A process for extracting uranium compounds from wet-process phosphoric acid (WPA) includes lowering iron content of WPA to produce a lowered iron WPA, reducing valency of any remaining iron in the lowered iron WPA to produce a reduced iron valency WPA. Uranium compounds are extracted from the reduced iron valency WPA via a solvent extraction process.
