  • Ion exchange recovery of gold from iodine–iodide

    2012-8-1 · Gold can be effectively recovered from iodide solutions using ion exchange resin. Triiodide loading is extremely strong and may be detrimental for gold loading. Triiodide is loaded as iodine by physiosorption releasing iodide back to solution. An eluant containing NaCl and Na2SO3 is very effective for gold and iodine elution.

  • Ways to Recover Gold from Cyanide Heap Leach

    2018-10-14 · Gold recovery from alkaline cyanide solution is typically accomplished by carbon adsorption or zinc cementation (Merrill Crowe). These and other emerging technologies, particularly resin ion exchange, solvent extraction, and direct

  • Gold Home DuPont

    2021-6-17 · Plating Baths. DuPont anion exchange resins, such as AmberSep™ 21K XLT Resin, are commonly used in the recovery of gold from spent plating bath solutions. Generally, the loaded resin will absorb up to 60 oz of gold per cubic foot (60 g/L) and the gold is

  • Figure 5 from Gold Selected Ion Exchange Resin vs

    The presence of copper in cyanide leach operations causes various operational problems, including increased cyanide consumption, increased toxicity of effluent and potentially lower gold recoveries. Changes to the “traditional” gold processing flowsheet and operating conditions are required to ensure maximum gold recovery at minimum operating expense.
