Rare earths (REs) playing key role in new modern lives; REs were having numerous applications in the areas of electrical, electronic fields. Hydrometallurgy is the cheapest and convenient for REs recovery from primary resources/secondary resources. The present experimental approach towards recovery of rare earths such as dysprosium and terbium from post-consumer waste of permanent magnets (PCWPMs) was designed and developed by hydrometallurgical approaches. Numerous phosphorous based extractants such as Cyanex 272, D2EHPA, PC 88A and TBP tested for suitable for REs separation and recovery. Kinetics of the extraction equilibria was studied. And as well as various pH conditions were tested and optimum condition was fixed for possible separation of each other REs. Scrubbing studies (crowding effect) was tested with dysprosium rich solution as scrub solution at different feed pH conditions. Finally, proper flowsheet for dysprosium separation from other REs was developed.
