sodium carbonates resulted in good gold elution. This was ascribed to the following exchange reaction mechanism [4] The better elution recoveries obtained with potassium carbonate implied that potassium aurocyanide was less firmly adsorbed than was sodium aurocyanide. This may be expected when the greater solubility of potassium
