Abstract Scope The solvent extraction of yttrium and neodymium from copper pregnant leach solutions (PLS) using Primene JM-T, a primary aliphatic amine, has been studied. Effect of contact time, pH, sulfate concentration, and extractant concentration were investigated using synthetic and actual PLS systems. Standard experimental conditions were 5 min contact time, pH 2.5, and 10 % v/v Primene JM-T concentration. Distribution isotherms were constructed for the pure system and for actual copper leach solutions. Synthetic solutions contained 100 ppm Y and Nd. Samples of PLS contained 2 - 10 ppm Nd and 14 - 30 ppm Y. Results showed that complete extraction of both yttrium and neodymium occurred within five minutes and at pH values greater than 1. It was also found that sulfate content does not inhibit extraction at any concentration. Additionally, the distribution isotherms created show that extraction for these metals can take place in one stage.
