Metal extraction device and method used in magnesium-iron-lanthanum production process

Abstract

The invention relates to the technical field of metal extraction, in particular to a metal extraction device and method used in the magnesium-iron-lanthanum production process, the metal extraction device comprises an outer wall barrel and a mixed mass transfer partition plate arranged in the outer wall barrel, and the lower portion of the mixed mass transfer partition plate is matched with the inner wall of the outer wall barrel to form a mixed mass transfer cavity; an impeller disc is arranged in the mixing mass transfer cavity, and liquid in the mixing mass transfer cavity is stirred through rotation of the impeller disc; according to the metal extraction device used in the magnesium-iron-lanthanum production process, when rare earth metal lanthanum is extracted from magnesium-iron-lanthanum mixed waste, mixed mass transfer can be conducted on extraction liquid and feed liquid, centrifugal separation is completed, the two steps are completed at the same time, and higher working efficiency is achieved.
