Book Description
An economical process was developed through benchscale experiments for recovering uranium from amine extractants with ammonium carbonate solution. By recycling the strip solution to allow build-up in the concentration of ammonium sulfate (formed in the stripping reactions) to 1-2M, the solubility of uranium in the aqueous phase was limited to 5 g/liter and ammonium uranyl tricarbonate (AUT) precipitated in the stripping system. The AUT, which settled and filtered rapidly, was readily converted to U3i by calcination at 5OO deg C, yielding a high assay (>97% U3O) concentrate virtually free of sodium, molybdenum, and vanadium. Estimated reagent costs for the strippingprecipitation step were 7 cent per pound of U3O. (auth).

Fifty oil soluble amines were screened for possible use as extractants for uranium from sulfuric acid solutions. The most promising of these were studied further to obtain the optimum conditions for operation of such a process. Kerosene was used as the diluent.

Book Description
Over 100 different organonitrogen compounds have been examined for their ability to extract uranium from aqueous solutions, particularly sulfate solutions, of the types usually encountered in uranium ore processing. The more promising of these have been examined further with respect to other characteristics essential to practical application, especially selectivity for uranium, reagent loss to the aqueous phase, compatibility with practicable diluents, maintenance of adequate extraction power over a range of liquor compositions, and compatibility with practicable stripping methods. Most of the compounds originally considered have been found worthy of only cursory examination. The important outcome on the other hand is that several compounds, specifically several long chain secondary and tertiary amines have been identified as having considerable promise for practicable solvent extraction application.
