    Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2 0.5 181;m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this 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.

  • Effect of Calcium on Gold Stripping Efficiency

    When calcium precipitates in the carbonate form onto the exterior surface of carbon it can also occlude fine ore particles. All of this impedes kinetic gold adsorption. Normal calcium loadings on carbon have no effect on elution that is why plants successfully acid wash either before or after elution /regeneration.
