Cyanide A cyanide is a chemical compound that contains the group CN. This group, known as the cyano group, consists of a carbon atom triple bonded to a nitrogen atom.[1] In inorganic cyanides, the cyanide group is present as the anion CN. For the salts such as sodium cyanide and potassium cyanide, these compounds are highly toxic.[2]

Dissolve Gold and Silver with Cyanide

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.
