ABSTRACT:
Wet process phosphoric acid is oxidized with nitric acid so that uranium values therein are in the +6 state. The organic extractant which contacts the acid extracts the +6 uranium and nitrate and/or nitrite ions. Urea is added to the oxidized acid to react with the nitrate and/or nitrite ions so that the organic does not extract them. The organic is reductively stripped with an aqueous solution containing ferrous ions. The efficacy of the ferrous ions is not lost through reaction with nitrate and/or nitrite ions.
