Abstract

The article discusses the processing of waste solutions of the AGMK copper plant, and as a result of research, a technology has been developed for producing refined palladium in powder and in ingot. Also, cleaning methods for reducing impurities in the composition of refined palladium are given. The results of aqua regia dissolution, advantages, leaching parameters are analyzed and methods for the selective precipitation of palladium from solutions are given, the maximum degree of purification of palladium using low-cost and simple technologies is substantiated, and to achieve high economic performance.
