Abstract

Изобретение относится к удалению двухвалентной меди из раствора хлорида меди при гидрометаллургическом производстве меди. В процессе производства меди медьсодержащее сырьё выщелачивают раствором, содержащим хлорид. Из образовавшегося при выщелачивании раствора хлорида меди, содержащего как одновалентную, так и двухвалентную медь, удаляют двухвалентную медь, по меньшей мере частично, путём осаждения, а раствор хлорида меди (I) направляют на дальнейшую обработку. Осаждение двухвалентной меди происходит в виде щелочного хлорида меди. Образовавшийся щелочной хлорид меди выщелачивают в виде хлорида меди (II) либо отдельно, либо при выщелачивании сырья, и используют при выщелачивании медьсодержащего сырья.Международная заявка была опубликована вместе с отчетом о международном поиске.
