Study of technological parameters of ion exchange resins and technology of recultivation of off-balance uranium-containing dumps

The article presents the technology of uranium extraction, the results of uranium extraction from recultivative dumps, physicochemical and technological properties of applied resins, as well as the state of radiation and ecological situation in the area of uranium ore mining enterprise location around the town of Uchkuduk (Uzbekistan). Nowadays, worldwide scientific research is being conducted on the return of technogenic waste to the main processing, application of high-quality sorbents based on chloride ions in the process of obtaining the finished product, uranium recovery in the process of sorption, improvement of the main indicators of uranium production and processing of technogenic dumps by means of their return. In this regard, it is necessary to develop physicchemical and technological fundamentals of technogenic waste processing, recultivation of sites, study the properties of anionites sorbing uranium in the process of uranium waste processing with highly concentrated solutions of chloride ions, pay special attention to scientific research on uranium extraction under conditions of seasonal low temperatures in the process of sorption.
