Abstract

Изучены возможности использования неметаллических катализирующих компонентов для биовыщелачивания металлов из низкосортных руд. Для ускорения растворения и повышения эффективности процесса предложены различные добавки (например, хлориды, йод, серосодержащие органические соединения, поверхностно-активные вещества и др.). Показано, что некоторые компоненты могут воздействовать на выщелачивание, ускоряя окисление сульфидных минералов, другие повышают проницаемость руды или улучшают доступность микроорганизмов к целевым металлам. Отмечается, что особый интерес представляет синергетический эффект от комбинации различных добавок.
