gold process and elution plant

  • Elution of gold from carbon by the micron solvent distillation procedure

    At 6580°C the elution of gold is fast and is not affected by water quality. The Micron procedure involves pretreatment of the loaded carbon with NaCN/NaOH followed by elution with methanol vapour and condensate. Carbon is packed into a column above the distillation pot and acts as a fractionating column. Recovery of.
