Sorption technology using anion exchange resin is used in the processing of gold-bearing ores of the Muruntau deposit. Studies have shown that despite the high selectivity for gold, silver and other associated non-ferrous metals, which are valuable from the point of view of the integrated use of mineral raw materials, are sorbed to some extent by ion-exchange resin. Studies have shown that it is possible in principle to extract silver from acidic waste solutions by precipitation using various precipitating reagents. This article presents the results of semi-industrial tests of the scheme for obtaining silver from waste solutions of ion exchange resin regeneration. The final product was a silver ingot with a metal content of 87,7%. In the future, anodes can be cast from the resulting silver ingot and 99,99% silver can be obtained by electrochemical method.
