Claims (4)

1. Способ сорбционного извлечения урана из растворов или пульп, содержащих также макро- и микропримеси, анионитами гелевой или пористой структуры, включающий насыщение анионита ураном, обработку насыщенного сорбента щелочным агентом и донасыщение анионита ураном, отличающийся тем, что донасыщение анионита ураном после щелочной обработки проводят при контактировании либо с исходным раствором (пульпой), либо с частью товарного десорбата.1. The method of sorption extraction of uranium from solutions or pulps also containing macro- and microimpurities, anions of a gel or porous structure, including saturation of the anion exchanger with uranium, treatment of the saturated sorbent with an alkaline agent and saturation of the anion exchanger with uranium, characterized in that the saturation of the anion exchanger with uranium is carried out after alkaline treatment in contact with either the initial solution (pulp), or with part of the product desorbate. 2. Способ по п.1, отличающийся тем, что к щелочному агенту на стадии обработки добавляют соль щелочного металла.2. The method according to claim 1, characterized in that an alkali metal salt is added to the alkaline agent in the processing step. 3. Способ по пп.1 и 2, отличающийся тем, что продолжительность операции донасыщения составляет 3÷7 ч.3. The method according to claims 1 and 2, characterized in that the duration of the operation of the saturation is 3 ÷ 7 hours 4. Способ по пп.1-3, отличающийся тем, что цикл операций, включающий обработку сорбента щелочью или щелочно-солевой смесью и донасыщение его ураном, повторяют несколько раз.4. The method according to claims 1 to 3, characterized in that the cycle of operations, including processing the sorbent with alkali or alkaline-salt mixture and its saturation with uranium, is repeated several times.
