Abstract

Способ относится к металлургии и может быть использован при извлечении драгоценных металлов, в частности платины, из электронного лома. Способ включает использование висмута с добавкой 1 мас.% индия в качестве коллектора платины в соотношении (от 2,0 до 2,5):1 к исходному материалу и окислительное рафинирование полученного расплава сплава висмут - платина воздухом при температуре 900-1000°С. Техническим результатом изобретения является упрощение и удешевление способа извлечения платины из отходов электронного лома.The method relates to metallurgy and can be used for the extraction of precious metals, in particular platinum, from electronic scrap. The method includes the use of bismuth with the addition of 1 wt% indium as a platinum collector in a ratio (from 2.0 to 2.5): 1 to the starting material and oxidative refining of the resulting bismuth-platinum alloy melt with air at a temperature of 900-1000 ° C. The technical result of the invention is to simplify and reduce the cost of the method for extracting platinum from electronic scrap waste.
