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.
Of these methods, ‘Cyanide Leaching Process’ or Cyanidation, is one main method that is highly and most often used for doing this procedure.

MAY 20, 1998, KYRGYZSTAN - A truck transporting cyanide to the Kumtor mine in Kyrgyzstan plunged off a bridge spilling almost two tons of sodium cyanide (1,762 kilograms) into local surface waters. Local people have reported at least 4 deaths that may have resulted from the spill.
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. It is the most commonly used leaching process for gold extraction.
In 1988, Cyanco (under the ownership of Mining Services International – MSI) undertook to build a liquid sodium cyanide plant in Winnemucca, Nevada, in the heart of gold mining country. Until this time, producers of sodium cyanide made a liquid product nearer to the raw materials, which was usually thousands of miles from where the mines were.

Gold cyanidation - Wikipedia, the free encyclopedia. The alkaline ore slurry can be combined with a solution of sodium cyanide or potassium cyanide, however many operations utilize calciumThis procedure can reduce concentrations of "Weak Acid Dissociable" (WAD) cyanide to below the 10 ppm mandated by the EU's Mining Waste Directive.
The discovery that metallic gold is soluble in potassium cyanide came after studying the action of cyanides on plates of gold, and announced that they were slowly dissolved. Metallurgists pointed out that gold-leaf is dissolved by a dilute solution of the salt, and also showed that if the gold floats on the surface of the liquid, so that one side of the leaf is in contact with the air, while ...
