Abstract
В данном документе раскрыт способ регенерации кислоты или основания в процессе извлечения металла. Способ содержит обеспечение контакта сырьевого потока, содержащего кислоту или основание и металл, с ультрафильтрационной мембраной для получения ультрафильтрационного ретентата и ультрафильтрационного пермеата, а также обеспечение контакта ультрафильтрационного пермеата с нанофильтрационной мембраной. Полученный нанофильтрационный ретентат содержит большую часть металла из сырьевого потока, а полученный нанофильтрационный пермеат содержит большую часть кислоты или основания из сырьевого потока. Также в данном документе раскрыто регенерирующее устройство для регенерации кислоты или основания в процессе извлечения металла.
