Abstract
1. Способ извлечения концентрата природного урана из сернокислых растворов подземного выщелачивания, включающий нитратно-сернокислотную десорбцию сорбента с операциями в технологической последовательности: отмывки анионита от минеральных взвесей, донасыщения анионита ураном из товарного регенерата, десорбции концентрата природного урана с анионита сернокислыми растворами аммиачной селитры, денитрации анионита с конверсией его в сульфатную форму, отмывки регенерированного анионита и осаждения концентрата природного урана с образованием маточного раствора от осаждения, а также образования дебалансного раствора: раствора с операции отмывки анионита от кислоты и фильтрата с фильтр-пресса, отличающийся тем, что образующийся дебалансный раствор возвращают в технологический процесс и объединяют с маточным раствором от осаждения концентрата природного урана и затем выводят через вышеупомянутую операцию донасыщения анионита совместно с товарным регенератом со стадии регенерации анионита на стадию сорбции.2. Отделение нитратно-сернокислотной десорбции, преимущественно при сернокислотном подземном выщелачивании концентрата природного урана с расположенными в технологической последовательности десорбционными колоннами, включающими десорбционную колонну донасыщения ионита из товарного регенерата, и связанными линиями коммуникаций с обеспечением противоточного движения ионита и десорбирующего раствора, а также трубоотводы маточного раствора от осаждения концентрата природного урана и дебалансного раствора: раствора с операции отмывки от кислоты и фильтрата с фильтр-пресса, отличающееся тем,1. A method of extracting natural uranium concentrate from sulfuric acid solutions of underground leaching, including nitrate-sulfuric acid desorption of the sorbent with operations in the technological sequence: washing anion exchange resin from mineral suspensions, additional saturation of anion exchange resin with uranium from commercial regenerate, desorption of natural uranium concentrate from anion exchange resin and sulfate solutions anion exchange resin with its conversion to the sulfate form, washing the regenerated anion exchange resin and the deposition of natural uranium concentrate with the image uterine solution from precipitation, as well as the formation of an unbalanced solution: a solution from the operation of washing anion exchange resin from acid and filtrate from a filter press, characterized in that the resulting unbalanced solution is returned to the process and combined with the mother solution from precipitation of natural uranium concentrate and then removed through the aforementioned operation of saturation of anion exchange resin together with commodity regenerate from the stage of regeneration of anion exchange resin to the stage of sorption. 2. The separation of nitrate-sulfuric acid desorption, mainly during sulfuric acid underground leaching of natural uranium concentrate with desorption columns arranged in a technological sequence, including a desorption column of an ion exchange saturation from a commodity regenerate, and connected communication lines to ensure countercurrent movement of an ion exchange resin and a desorption solution, as well as a piping from the mother liquor deposition of natural uranium concentrate and unbalanced solution: solution from washing operation and from acid and filtrate from a filter press, characterized in that
