Abstract
1. Способ переработки уранфторсодержащих отходов, включающий сернокислотную обработку твердых отходов с получением сульфатно-фторидного раствора и его экстракционную очистку от примесей, отличающийся тем, что сульфатно-фторидный раствор перед экстракцией направляют на сорбционную очистку от Мо и W, при этом используют сорбент на основе оксида титана с содержанием 5 мол.% оксида циркония, а в сульфатно-фторидный раствор перед сорбционной очисткой вводят сульфат алюминия в соотношении Al:F=1:6. ! 2. Способ по п.1, отличающийся тем, что сорбент по мере насыщения молибденом и вольфрамом подвергают регенерации и возвращают в сорбционный цикл. ! 3. Способ по п.2, отличающийся тем, что регенерацию сорбента ведут в две стадии, на первой - десорбируют уран, на второй - молибден и вольфрам. ! 4. Способ по п.3, отличающийся тем, что уран десорбируют водным раствором бикарбоната аммония с концентрацией 50-100 г/л. ! 5. Способ по п.3, отличающийся тем, что молибден и вольфрам десорбируют водным раствором гидроксида натрия с концентрацией 50-100 г/л. 1. A method of processing uranium fluoride-containing wastes, including sulfuric acid treatment of solid wastes to obtain a sulfate-fluoride solution and its extraction purification from impurities, characterized in that the sulfate-fluoride solution before extraction is sent to sorption purification from Mo and W, using a sorbent based on titanium oxide with a content of 5 mol.% zirconium oxide, and aluminum sulfate in the ratio Al: F = 1: 6 is introduced into the sulfate-fluoride solution before sorption purification. ! 2. The method according to claim 1, characterized in that the sorbent is subjected to regeneration as it is saturated with molybdenum and tungsten and returned to the sorption cycle. ! 3. The method according to claim 2, characterized in that the regeneration of the sorbent is carried out in two stages, in the first - uranium is desorbed, in the second - molybdenum and tungsten. ! 4. The method according to claim 3, characterized in that the uranium is desorbed with an aqueous solution of ammonium bicarbonate with a concentration of 50-100 g / L. ! 5. The method according to claim 3, characterized in that molybdenum and tungsten are desorbed with an aqueous solution of sodium hydroxide with a concentration of 50-100 g / l.
