Gold recovery with ion exchange used resins

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

The recovery of gold from ammoniacal thiosulfate

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.
