Requirement of automation and clean processes for solvent extraction of rare earths

Abstract

Rare earths have been emphasized on the advanced materials for which rare earth products are required to be high purity. To produce high quality products,the solvent extraction should be controlled by automation system and operated in clean process This article proposes the automation and dean process of solvent extraction system far producation of high quality rare earth compounds Those are a fine control of Bow rate with feedback of analytical data by on-line analytical system in the clean environmental operation.
