The mechanism of elution of gold cyanide from activated

Numerous articles have appeared on the mechanism of the adsorption of gold cyanide onto activated carbon. In contrast, little information is available on the mechanism of elution of the adsorbed gold. It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly. The presence of ...

2010-1-1  A new elution process for recovering gold thiosulfate from resins is described, and is based on the concept of synergistic ion exchange. In the presence of sulfite, Au(S 2 O 3) 2 3− is converted to Au(S 2 O 3)(SO 3) 3−, which has a reduced affinity for strong anion exchange resins and is shown to be readily eluted by weaker eluants, such as chloride.. Chloride has several advantages over ...
