Abstract
Recently, one of the main directions for increasing the extraction of uranium from difficult-to-hide ores is the use of intensifiers, which allow the most complete transfer of uranium from one valence state to another. In the article, the catalyst “M-1”, which is a compound of transition metals, is considered as an intensifier. Comparison of the kinetic dependencies of the sorption extraction of uranium by the ionites from the productive solutions of leaching of uranium-bearing ore in the presence of the “M-1” catalyst showed that they differ insignificantly. The possibility of sorption of uranium from productive solutions by natural sorbents in comparison with synthetic sorbents is investigated.
