Abstract

<p>Nowadays, in the given conditions of Uzbekistan, there is hardly any comprehensive&nbsp;technology either for processing of industrial waste or extraction of rare and precious metals&nbsp;at the JSC &ldquo;AGMK&rdquo; with small amounts of rare metals. The presence of the man-made waste&nbsp;containing platinum, palladium and rhodium in AGMK JSC indicates that the plant can manage&nbsp;the industry, having been processing the waste for several years without recycling the ore. This&nbsp;article discusses the feasibility of combining the products of enrichment of metallurgical waste&nbsp;and of extracting of platinum and palladium from industrial waste - copper red mud. This work&nbsp;defines the effectiveness of methods for selective leaching of platinum and palladium as well as&nbsp;it focuses on methods of dissolution, reduction of platinum metals and their purification from&nbsp;<br /> various impurities. A fundamental hydrometallurgical comprehensive technology for extraction of&nbsp;platinum and palladium with multistage refining processes has been developed as a result of the&nbsp;research.</p>
