Abstract
The possibility of associated rhenium extraction during complex processing of productive solutions of underground uranium leaching (UL), by means of precipitation and membrane methods with the use of cationic water-soluble polyelectrolites (PE) is shown. High-molecular nitrogen-containing substances are used as PE ( BA series; as well as pilot models, developed in the Mendeleyev Russian Chemical and Technological University). It has been established that rhenium extraction from sulphuric productive solutions of UL with the use of complexation
