Abstract

A process is described for the recovery of uranium form wet-process phosphoric acid utilizing an alkyl pyro-phosphoric extractant. the extractant also contains a modifier for retaining the alkyl pyrophosphoric aicd in solution in an essentially water-immiscible organic diluent during stripping, after extracting the uranium from wet-process acid, the APPA extractant is treated with an oxidizing agent such as hydrogen peroxide and the uranium stripped into an alkaline stripping solution. the alkaline stripping solution is an aqueous solution of an alkali metal or ammonium carbonate or hydroxide. the barren extractant is recycled for contacting with fresh wet-process acid. the uranium and any ferric iron present is precipitated in the stripping solution. the uranium is dissolved in an aqueous solution such as an aqueous solution of ammonium uranyl tricarbonate (AUT), any precipitated ferric solids are separated from the solution , and the uranium is reprecipitated , separated, dried and calcined to a U3O8 product.
