Wawasan Wiyata Mandala Power Point11/13/2022 Separation of rare earths is a challenging task and over the years many separation schemes based on solvent extraction, ion exchange, membrane etc have been developed and deployed. Rare earths have been a very fascinating area of research since long due to its wide applicability's in many field including superconductors, lasers, phosphors, medical, electronics, magnet, optics etc. Studies on the adsorption behaviour of heavy rare earths with a strong cation exchanger DOWEX 50 W-2 X 8 Separation of copper and nickel was not conclusively observed at any of the conditions examined Distribution ratios were compared with those previously obtained from a continuous annular chromatographic system. Results were determined for different feed concentrations, as well as for different concentrations and pH values of the ammonium carbonate eluant. Pressurized ion exchange on Dowex 50 W-X 8 and 50 W-X12 resins was investigated using elution techniques to determine distribution ratios for copper, nickel, and cobalt complexes contained in ammonium carbonate solution, a mixture which approximates the waste liquor from the Caron nickel recovery process.
