Abstract

Изобретение относится к способу селективного выделения урана из сульфатного кислого водного раствора урана, содержащего железо и другие металлы, с помощью экстракции растворителем, в котором используемый экстрагент в органическом экстрагирующем растворе представляет собой бис-(2-этилгексил)фосфат, а модифицирующий агент представляет собой жидкий разветвленный триалкилфосфиноксид. Способ характеризуется тем, что концентрация урана в исходном растворе составляет 50 мг/л, а в водный и/или экстрагирующий растворы вводят восстанавливающий агент для предотвращения постоянного окисления железа до трехвалентного состояния. В данном способе большая часть экстрагирующего раствора циркулирует по контуру, состоящему из стадии экстракции и резервуара-хранилища, и только малую часть экстрагирующего раствора, содержащего уран, направляют на отмывку и реэкстракцию.
