Gold cyanidation Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction. . The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au(s) + 8 NaCN(aq).
