Abstract
Mintek has been involved in the development of ion-exchange technologies for the gold industry for more than 25 years. These technologies include the development of gold-selective anionexchange resins, design and engineering aspects of resin-in-pulp and resin-in-solution for the recovery of gold, and the use of ion exchange for the recovery and recycling of cyanide. More recently, an automated ion-exchange process was developed to recover gold powder from carbon eluate in an attempt to limit gold theft during the final stages of processing.
