  • How Is Mercury Used to Purify Gold? | Sciencing

    Miners submerged their ore in mercury, which would take on the gold but not the other impurities. The mixture of mercury and gold would then be recollected and heated until the mercury boiled away. A simple still like those used to make alcohol would draw away the vaporized mercury, possibly collecting it for reuse, leaving mostly pure gold.

  • Elution and Carbon Reactivation Resource book

    During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
