ABSTRACT:
A method is disclosed for separating uranium from molybdenum in an aqueous solution. The pH of the solution is lowered to about 1 to about 4 using an inorganic acid such as hydrochloric acid. The carbon dioxide is then removed from the solution which can be done by aeration. The pH of the solution is raised to about 9 in the presence of ammonium ions which result in the precipitation of ammonium diuranate. The precipitated ammonium diuranate may then be filtered or otherwise separated from the molybdenum which remains in the solution.
