Sodium Cyanide Solution Cyanide For Gold Extraction AGR

Using sodium cyanide solution also eliminates the use of chemicals, such as caustic soda, to maintain a stable pH level when dissolving solid sodium cyanide. Water quality, in particular salinity, can significantly destabilise the pH balance in the dissolution process.

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex.
