METHOD OF SOLID-PHASE DESORPTION OF URANIUM Russian patent published in 2003 - IPC

Abstract RU 2203856 C2

FIELD: extraction of uranium by sorption. SUBSTANCE: desorption of uranium is performed from sorbent saturated by ammonium carbonate solutions. Uranium is extracted in form of crystalline salts. Ammonium sulfate is introduced into desorbing solution to concentration of 100-400 g/l. EFFECT: reduced residual capacitance of sorbent; increased yield of uranium; enhanced purity of salts. 1 tbl
