Abstract

Раскрыт способ выщелачивания ценных металлов из оксидных материалов, таких как латеритовая никелевая руда, включающий стадию выщелачивания руды выщелачивателем, содержащим катионную соль (например, хлорид магния) и хлористо-водородную кислоту. Может быть добавлен окислитель или дополнительный хлорид металла (например, образующийся в результате операции выщелачивания). В одном из примеров осуществления изобретения способ включает в себя выделение ценного металла из руды, включающее стадии выщелачивания руды выщелачивателем; отделения обогащенного ценным металлом щелока в ходе первого разделения жидкости и твердого вещества; окисления и нейтрализации обогащенного ценным металлом щелока, полученного таким способом; и отделение раствора хлорида магния от полученного таким способом щелока в ходе второго разделения жидкости и твердого вещества. В другом примере осуществления изобретения раствор выщелачивателя регенерируют из раствора хлорида магния. В следующем примере осуществления изобретения регенерация раствора выщелачивателя включает в себя стадию получения оксида магния из раствора хлорида магния.
