A New Process for Cobalt Nickel Separation

2015-11-20  A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
