This invention relates to a process for treating a resin that has been in contact with pregnant leach solution (PLS) containing ionic metal species such as uranium, copper, cobalt, nickel, gold, chrome, PGM's and Rare Earth Metals, and which is loaded with the ionic metal species in an ion exchange loading system (10). Loaded resin (12) from the ion exchange loading system (10) is subjected to a multi-vessel continuous counter- current ion exchange (CCIX) system (34) to remove the metal species from the resin and obtain a regenerated resin essentially free of the metai species, which may be recycled to an ion exchange loading system where it is placed again in contact with the PLS. |
