GOLD AND SILVER

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.

UTILIZING CYANIDE RECOVERY TECHNIQUES IN

Cyanide in solution is combined with gold ore and leaches the metal to form a soluble cyanide gold complex. The gold is then typically adsorbed onto activated carbon for downstream recovery. The resulting barren solution, still containing cyanide but absent of gold, can then be recycled for reuse and leaching of new ore.
