METHOD OF SORPTION RECOVERY OF URANIUM FROM SILICON-CONTAINING SOLUTIONS AND PULSE Russian patent published in 2000 - IPC

Abstract RU 2159216 C1

FIELD: methods of uranium recovery by sorption. SUBSTANCE: uranium from silicon-containing solutions and pulse is recovered with highly basic anionite of gel or porous structure. Saturated anionite in amount of 10-100% is treated with solution of sodium hydroxide at pH 4-13. Treated ionite is repeatedly contacted with initial solution or pulp. EFFECT: higher sorption capacity of uranium in waste solutions and on ionites after desorption, prevented poisoning of ionite with silicon. 2 cl, 1 tbl
