    Carbon ElutionStrip 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 ...

    A high-pressure laboratory elution rig was commissioned to simulate industrial Zadra and AARL elution conditions for the stripping of gold, silver and mercury from loaded activated carbon. It was found that cyanide was essential for the efficient elution of both mercury and silver, while gold was found to elute most effectively in hot, low-ionic strength solutions.
