Claims (2)

1. Способ переработки продуктов, содержащих халькогениды неблагородных металлов, металлы платиновой группы и золото, включающий плавку с добавками медьсодержащих и (или) железосодержащих материалов, натрийсодержащих флюсов и углеродистого восстановителя, отстаивание и охлаждение расплава до затвердевания, разделение затвердевшего продукта по образовавшимся границам раздела фаз, измельчение выделенной тяжелой донной фазы в порошок и его переработку как концентрата аффинажного производства, отличающийся тем, что исходные продукты, содержащие халькогениды неблагородных металлов, металлы платиновой группы и золото, перед плавкой обрабатывают раствором азотной кислоты до окислительно-восстановителыюго потенциала (500-700) мВ, а не растворившиеся остатки плавят с добавками медьсодержащих и (или) железосодержащих промпродуктов, полученных при гидролитической или цементационной обработке растворов аффинажного производства.1. A method of processing products containing non-base metal chalcogenides, platinum group metals and gold, including smelting with the addition of copper-containing and (or) iron-containing materials, sodium-containing fluxes and a carbon reducing agent, sedimentation and cooling of the melt before solidification, separation of the solidified product along the formed phase interfaces , grinding the selected heavy bottom phase into powder and its processing as a concentrate of refining production, characterized in that the starting products, with base chalcogenides of base metals, platinum group metals and gold, are treated with a solution of nitric acid to a redox potential (500-700) mV before melting, and non-dissolved residues are melted with additives of copper-containing and (or) iron-containing intermediate products obtained by hydrolytic or cementation treatment refining solutions. 2. Способ по п.1, отличающийся тем, что медьсодержащие и (или) железосодержащие материалы добавляют в количестве от 50 до 200% от массы не растворившегося в азотной кислоте остатка.2. The method according to claim 1, characterized in that the copper-containing and (or) iron-containing materials are added in an amount of from 50 to 200% by weight of the residue which is not dissolved in nitric acid.
