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

The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation This process is more frequently referred to as leaching As well as reacting with the precious metals the cyanide will react with iron copper or zinc that may be in the ore In order to leach the
