Carbon Elution/Strip System for precious metal recovery

During the standard elution process, the majority of the gold is recovered in the first half of the strip cycle and the remaining time is used to polish the carbon to low absorbed gold values. In our patented FLS-SVT Split-Zadra, as is true for the Split-AARL process, the solution from the polishing time is used as the lean eluate for the next elution cycle.

Factors affecting the elution of gold cyanide from …

The elution of gold cyanide is suppressed by the presence of cations (Mn+) through the formation of Mn+ (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. High temperatures and intense cyanide pre-treatment, i.e. conditions ...
