ION EXCHANGE PROCESS FOR SEPARATION OF IRON (III) IONS FROM AQUEOUS SULFURIC ACID METAL ION-CONTAINING SOLUTIONS.

摘要

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.
