Cyanide (HCN, hydrogen cyanide) and its salts, such as potassium cyanide (KCN) and sodium cyanide (NaCN) are used in numerous of industrial processes, electroplating of metals, chemical synthesis, and extraction of gold or silver.
However gold does dissolve in aqueous cyanide solutions in the presence of air. Reaction of gold with water. Gold does not react with water. Reaction of gold with the halogens. Gold metal reacts with chlorine, Cl 2, or bromine, Br 2, to form the trihalides gold(III) chloride, AuCl 3, .

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex.
Corrosion tables The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions. The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.

Potassium cyanide is a compound with the formula K CN. This colorless crystalline salt, similar in appearance to sugar, is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewelry for chemical gilding and buffing. [19] Potassium cyanide is highly toxic.
