Abstract

Disclosed is a method for separating a rare-earth by coupled recycling of materials. The method comprises: using an organic phase prepared by mixing an extractant A and a rare-earth soap stock and loaded with the rare-earth for a subsequent coupled extraction separation, and re-using same in dissolution of raw materials after extracting C and concentrating the inorganic acid in the remaining water phase or recycling same after precipitating the rare-earth therein with oxalic acid; extracting the rare-earth solution after purification by separation, using oxalic acid to precipitate the rare-earth, and using the remaining inorganic acid directly for washing, for a reverse extraction process, or for dissolving raw materials after extraction and concentration. The method can recycle the intermediate materials produced during the rare-earth separation among process sections, can avoid the alkaline saponification of the extraction, and can achieve processes such as dissolution, washing and reverse extraction of the raw materials by only using the recycled inorganic acid.
