Gold recovery via Ion exchange resins. An abstract of a stone to be presented by Ben Strong at ALTA 2017. ABSTRACT. Ion exchange resins, that are semi-selective for gold, have been extensively used for gold recovery from cyanide leach processes in the former USSR. Despite forward looking statements by researchers and technology vendors, there

2001-6-1 The cationic resin could not recover gold from the solution and was then eliminated as a candidate for the job. The measured concentration histories in the solutions in contact with the anionic resins are shown in Fig. 4, while in Fig. 5 the amounts recovered by the resins, calculated with Eq. (5), are shown.These figures clearly show that, when NaOH is used as regenerant, the weak base resin

2020-8-28 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 recovered by thermal decomposition (fuming).

2020-2-10 performed on the pregnant leach liquor prior to gold recovery could cause gold loss, especially if a high removal efficiency of copper cyanide is required prior to gold recovery. This stone discusses the use of a commercially available ion exchange resin with an exceptionally high selectivity for gold over copper.

2004-3-1 Obviously, gold was first stripped from the resin and then decomposed due to the lack of complexing agent. The addition of 0.1 M ATS prevented gold deposition. However, gold elution was not satisfactory using 2 M NaCl, with gold recoveries being only 71.8% and 82.1% at 37 and 52 BV, respectively. Copper elution was also somewhat reduced.
