    High gold cyanide and cation concentrations, low temperatures, low anion concentrations and active carbon drive the gold cyanide onto the carbon. During elution, lack of cations (Ca2+, Mg2+, etc), high anion concentration (CN , OH ) and high temperatures will disrupt the equilibrium and remove gold cyanide from the carbon.
