Abstract
This study designed a counter current extraction process for comparing the separation efficiencies that are obtained using Cyanex 572 and PC88A for the elements in a Pr and Nd mixed solution. This process involves multiple extraction and scrubbing processes using a mixer settler. The process parameters are calculated using an.....

DOI:
https://doi.org/10.3365/KJMM.2018.56.2.146
Abstract
Solvent extraction of La, Ce, Pr, Nd and Sm from chloride solutions was studied using PC88A and Cyanex 572 as the extractants. Our results indicated that the acidity of the aqueous solution and saponification degree had some effect on the percentage extraction of metal ions. The distribution coefficient of the.....
