Claims (4)

1. Способ получения селективных концентратов благородных металлов из шламов электролиза меди и никеля или полупродуктов их переработки, содержащих металлы платиновой группы, золото, серебро, селен, включающий обработку серной кислотой с последующим выделением металлов-спутников платины и серебра из сульфатного раствора, отличающийся тем, что для отделения серебра, селена и спутников платины от платины, палладия и золота шламы или полупродукты их переработки подвергают окислительному выщелачиванию в сернокислом растворе в автоклаве.1. The method of obtaining selective concentrates of precious metals from sludges of electrolysis of copper and nickel or intermediates of their processing containing platinum group metals, gold, silver, selenium, including treatment with sulfuric acid, followed by separation of platinum and silver satellite metals from a sulfate solution, characterized in that to separate silver, selenium and platinum moons from platinum, palladium and gold, sludges or intermediates of their processing are subjected to oxidative leaching in a sulfuric acid solution in an autoclave. 2.
