Abstract
Изобретение относится к объединению процессов выщелачивания карбонатом аммония с освоенными процессами кислотного или щелочного выщелачивания урана в многофункциональные промышленные процессы, обеспечивающие экстракцию, глубокую очистку и переработку обогащенного или частично обогащенного урана, такого как UOUOили большинство четырех- и шестивалентных форм урана, а в случае целесообразности и извлечение урана из урановых руд с использованием передовых многостадийных мембранных технологий для концентрирования и отделения урана в растворе от тяжелых металлов и более легких элементов, которые могут присутствовать в растворе, а также с использованием способности аммонийно-карбонатного выщелачивающего реагента к селективному выщелачиванию и осаждению.
