Изобретение относится к методу обработки сложных металлических сульфидных материалов и к методу для извлечения металлов из таких материалов. Процесс отличается тем, что материал сначала подвергается выщелачивающей обработке в таких условиях, при которых сульфидная сера окисляется в сульфат, а окисленное железо и примеси, такие как Аs, переходят в раствор, после чего осадок выщелачивания плавится для извлечения металла обычным пирометаллургическим методом. Изобретение также относится к применению различных вариантов метода для получения драгоценных металлов из тугоплавких материалов, содержащих такие металлы, и для извлечения металла из сложного медного концентрата и сложного никелевого концентрата.The invention relates to a method for processing complex metal sulfide materials and to a method for extracting metals from such materials. The process is characterized in that the material is first leached under conditions in which sulfide sulfur is oxidized to sulfate, and oxidized iron and impurities, such as As, are transferred to the solution, after which the leach precipitate is melted to extract the metal by the usual pyrometallurgical method. The invention also relates to the use of various variants of the method for producing precious metals from refractory materials containing such metals, and for extracting metal from complex copper concentrate and complex nickel concentrate.
