Изобретение относится к технологии регенерации водных хлоридных щелоков от выщелачивания. Способ включает обжиг водного хлоридного щелока от выщелачивания с образованием оксида металла и газа, содержащего хлористый водород. Газ, содержащий хлористый водород, пропускают через предконцентратор, где он контактирует с отработанным водным хлоридным щелоком от выщелачивания. Пропускание газа приводит к испарению воды из отработанного рассола и его концентрированию. Одновременно отработанная жидкость абсорбирует хлористый водород. Хлористый водород, не абсорбированный в предконцентраторе, контактирует с водой, образуя соляную кислоту. Соляная кислота может быть смешана с концентрированной отработанной жидкостью и может быть использована повторно. Также раскрывается устройство для осуществления этого способа.The invention relates to a technology for the regeneration of aqueous chloride liquor from leaching. The method involves calcining aqueous chloride liquor from leaching to form metal oxide and a gas containing hydrogen chloride. A gas containing hydrogen chloride is passed through a pre-concentrator, where it contacts the spent aqueous chloride liquor from leaching. The passage of gas leads to the evaporation of water from the spent brine and its concentration. At the same time, the spent liquid absorbs hydrogen chloride. Hydrogen chloride, not absorbed in the pre-concentrator, is in contact with water, forming hydrochloric acid. Hydrochloric acid can be mixed with concentrated spent liquid and can be reused. A device for implementing this method is also disclosed.
