Description

варительное снижение содержани  суль фат-иона в фосфорной кислоте. Совокупность признаков позвол ет повысить степень изЬлечени  до 98%. .Примеры 1-4 .К 100 г фосфорной кислоты-с концентрацией 52% добавл ют 4 г железа, через получен ный раствор продувают фтористый водо род с добавлением в раствор различ ных количеств ацетона и метилэтилке на (МЭК). Результаты представлены в табл.1. Примеры 5-10, К 100 г фосфорной кислоты, содержащей, вес.%.. 29,1} SiOi 0,72 А1 0,23, ,5-, К 0,04; Са 0,62; Е 1,6; Ре 0,25; и 120 ррт, добавл ют 4 г железа. Смесь перемешивают в течение 30 мин,- после чего остатки железа извлекают. К раствору добавл ют различные количества фтористого ам- . мони  и алифатического кетона, IGзультаты представлены в табл,2. Примеры 11-17. к 100 г фосфорной кислоты того же состава, что и в примерах 5-9, добавл ют карбонат бари , железо и различные количества фтористого водорода и растворител . Результаты представлены в табл.3. Как видно .из приведённых результатов , при подаче осадител  менее 0,05% снижаетс  степень извлечени , а подавать более 7% нецелесообразно. Предварительное осаждение сульфатионов позвол ет снизить расход органического растворител . Таким образом, предлагаемый способ позвол ет повысить степень извлечени  урана, а также чистоту получаемой кислоты. . Таблица 1A dramatic decrease in the content of sulfate ion in phosphoric acid. The combination of features allows increasing the recovery rate to 98%. . Examples 1-4. To 100 g of phosphoric acid — with a concentration of 52%, 4 g of iron are added; hydrogen fluoride is blown through the resulting solution with various amounts of acetone and methyl ethyl (MEK) added to the solution. The results are presented in table 1. Examples 5-10, K 100 g of phosphoric acid, containing, wt.% .. 29.1} SiOi 0.72 A1 0.23;, 5-, K 0.04; Ca 0.62; E 1.6; Re 0.25; and 120 ppm add 4 g of iron. The mixture is stirred for 30 minutes, after which iron residues are removed. Different amounts of amoric fluoride are added to the solution. moni and aliphatic ketone, IG results are presented in Table 2. Examples 11-17. to 100 g of phosphoric acid of the same composition as in examples 5-9, barium carbonate, iron and various amounts of hydrogen fluoride and solvent are added. The results are presented in table 3. As can be seen. From the above results, when the precipitant is supplied less than 0.05%, the recovery rate decreases, and it is impractical to supply more than 7%. The preliminary precipitation of sulfations allows the consumption of organic solvent to be reduced. Thus, the proposed method allows to increase the degree of extraction of uranium, as well as the purity of the resulting acid. . Table 1
