An ion exchange separation, recovery and regeneration process for the control of iron has been developed to replace the conventional bleed stream process used in copper electrowinning. The process minimizes the loss of cobalt from the electrowinning circuit and strips the iron into a sulfate-based solution suitable for leach solution makeup. In addition, this process can effect a lowering of the total iron concentration in the electrolyte circuit with an associated increase in current efficiency.

Un procédé de régénération, de récupération, de séparation et d'échange d'ions pour contrôler la présence de fer a été mis au point afin de remplacer le procédé classique de purge utilisé au cours de la récupération électrolytique du cuivre. Le procédé permet de minimiser la perte de cobalt dans le circuit de récupération électrolitique et de dissoudre le fer dans une solution à base de sulfate qui peut être utilisée pour faire une liqueur lixiviante. De plus, le procédé peut permettre de réduire la concentration totale de fer dans le circuit de récupération électrolytique et en améliorer l'efficacité.
