DEVELOPMENT OF A SOLVENT EXTRACTION PROCESS FOR …

separation of light from middle and heavy rare earths should be around 1.0, the pH for the separation of Nd from La, Ce and Pr should be around 1.4 and the separation of Nd from Ce and Pr would require many extraction and scrubbing stages Semi continuous tests were carried out to develop the solvent extraction process in three separate circuits.
