Factors affecting the elution of gold cyanide from ...

1994-1-1  Adams and Nicol [4] listed the most significant influences on elution, in order of decreasing importance, as follows : temperature, cyanide and hydroxide concentrations, and the ionic strength of the eluant. Likewise, Davidson [5] considered the temperature and reagent cyanide addition to be the most important factors affecting gold elution.

Factors affecting the elution of gold cyanide from ...

The elution of gold cyanide is suppressed by the presence of cations (M n+) through the formation of M n+ (Au (CN) 2−) on the carbon. The horizontal position of the gold peak in an AARL elution profile was found to be a function of the elution of the cations from the carbon bed.
