Intensification of ion-exchange extraction of uranium from silicon-containing solutions and pulps

A method is proposed for intensifying sorption extraction of uranium from s ilicon-containing solutions and pulps using strongly basic anionites with g el and porous structure. The method decreases the degree of poisoning of th e sorbent by silicon compounds, increases the saturation capacity of the so rbent with respect to the uranium reaching desorption, aril decreases the c oncentration of uranium in the waste solutions: A multicyclic process of so rption-desorption of uranium tinder conditions where polymer forms of urany l are formed was studied. The technological scheme of the silicon desorptio n process is presented. 3 figures; 2 tables, 6 references.
