Investigation of Mercury Reduction in Gold Stripping ...

80oC removed very little gold from carbon as compared with industrial standard HCl acid washing, 0.25% versus 0.96%. At 80oC, only minimum amount of mercury was reduced and volatilized. Based on this study, mercury removal from the gold loaded carbon prior to the downstream process (gold stripping, electrowinning and carbon regeneration) minimizes

A process is disclosed for the recovery of gold and/or silver values from activated carbon, wherein they are adsorbed as cyanide complexes. The process uses an eluant containing sugar. The process allows the eluant to pass through fresh carbon twice, thereby reducing the volume of the gold-loaded eluant. This, in turn, reduces the size of the electrowinning or zinc precipitation circuits.

Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
