Abstract

Способ и установка для удаления мышьяка из мышьякосодержащего материала. Способ включает в себя стадии контактирования мышьякосодержащего материала с агентом выщелачивания мышьяка для образования мышьякосодержащего раствора и обедненный мышьяком твердой фазы. Агент выщелачивания может быть неорганической солью, неорганической кислотой, органической кислотой и/или щелочным реагентом. Обедненную мышьяком твердую фазу отделяют от мышьякосодержащего раствора, который приводится в контакт с агентом связывания с получением обедненного мышьяком раствора и нагруженного мышьяком агента связывания. Агент связывания содержит соединение, содержащее редкоземельные элементы, которое может включать церий, лантан или празеодимий. Затем агент связывания отделяют от обедненного мышьяком раствора. Извлекаемый металл в обедненной мышьяком твердой фазе, мышьякосодержащем растворе или обедненном мышьяком растворе может быть отделен и собран. Извлекаемые металлы могут включать в себя металл группы IA, группы IIА, группы VIII и переходные металлы.
