Abstract

Настоящее изобретение вообще имеет отношение к созданию процесса производства серной кислоты и к извлечению металлов, таких как медь и драгоценные металлы, из материалов, содержащих серу, при помощи операций автоклавного выщелачивания. В соответствии с различными аспектами настоящего изобретения, содержащие серу материалы могут содержать остатки из операций автоклавного выщелачивания, например из операций, проводимых при средних температурах. Способ в соответствии с настоящим изобретением преимущественно может быть использован для конверсии таких содержащих серу материалов в серную кислоту при помощи автоклавного выщелачивания. Полученная таким образом серная кислота с успехом может быть использована в других операциях обработки минералов, например, проводимых на месте ее получения. Металлы, такие как драгоценные металлы, которые имеются в содержащих серу материалах, с успехом могут быть извлечены из продукта обработки при помощи известных технологий извлечения драгоценных металлов.Отчет о международном поиске был опубликован 2002.06.06.
