Abstract
Currently, geotechnological methods of mining have become widespread in Uzbekistan and abroad, which have several serious advantages over the traditional labor-intensive mining method. Among them, geotechnologies of underground (in-situ) leaching of uranium, rhenium, copper, nickel, iron, zinc, aluminum, gold, etc. occupy a special place. Depending on the hydrogeological conditions of the ore body and the chemical composition of minerals, for each deposit prepared for uranium extraction by the in-situ leaching method, not only a thorough study of the reagent leaching scheme is required, but also a reasonable choice of technology for further processing of productive solutions. It is known that the presence of a significant amount of chloride ions, as a result of their competitive influence, suppresses the sorption of uranium from productive solutions and leads to a significant decrease in the capacity of resins. Therefore, the study of the technology of uranium extraction from sulfuric acid productive solutions with a high content of chloride ions is undoubtedly an urgent task.
