    The sodium cyanide solution is then transferred to the Cyanide Distribution Tank for use in the process. Sodium cyanide is metered from the Cyanide Distribution Tank into the Barren Solution Sump, as makeup for the heap leach process, at a flowrate of 0.2 gallons per minute ("gpm").

  • Kinetics and reaction mechanism of gold cyanidation

    The current status of the mechanism of gold cyanidation based on diffusion and surface adsorption–reaction models are reviewed. Published rate data based on chemical oxidation from flat gold surfaces in pure aerated cyanide solutions are analysed to show a reaction order of 2.7 with respect to cyanide at low concentrations.
