Elution - an overview ScienceDirect Topics

All of the stripping operations are carried out at 55–60 °C and atmospheric pressure. The original design of the stripping section required up to 288 h (12 days) for elution before achieving gold recovery. In the 1980s, a new stripping technique was developed, which takes from 12 to 24 h, a considerable improvement over the original design.

TECHNICAL PAPER - Ion Exchange Resin Manufacturer

2020-2-10  Due to the strong affinity of these resins for gold-cyanide anions, elution of the loaded precious metals is difficult and a sulphuric acid/thiourea mixture is most commonly used. During elution, the negatively charged gold-cyanide complex is broken and a positively charged gold-thiourea complex is formed, as shown in Reaction 6. The resin has no affinity for the positively charged gold-thiourea complex and the gold reports to the eluate
