<p>A purification process for a gold-containing iodine solution, or pregnant, gold-bearing iodine lixiviant, that results from the leaching of a gold-containing material with an iodine/iodide lixiviant solution. The process involves purification of the gold-bearing iodine lixiviant produced by a lixivial process, such as in situ, heap, vat, or agitated leaching, with a certain type of strongly acidic cation-exchange resin to facilitate subsequent recovery of gold and regeneration and recycling of the iodine lixiviant by electrolysis, thus making possible pollution-free, efficient recovery of gold.</p> |
