The mining industry has generally been slow to apply ion exchange processes to hydrometallurgical applications even if ion exchange offers an ideal solution for a particular problem. Two notable exceptions are in gold and uranium recovery. The largest application of ion exchange in the metals processing industry has been the use of resin-in-pulp (RIP) for gold recovery as an alternative to activated carbon. Iron is a ubiquitous impurity in hydrometallurgical solutions, and bulk removal of iron is often accomplished by precipitation, which can lead to co-precipitation losses of base metals. Increasingly, ion exchange is favored for the removal of smaller amounts of iron from process solutions. This paper provides an overview of the applications and commercial scale developments of ion exchange for iron removal from various metal processing solutions, including Cu, Ni, and Co solutions. It reviews several case studies that discuss operational and resin regeneration strategies as well as the impact of improved iron control on the commercial operations of metal processing.
