What cyanide is Cyanide is a rapidly acting, potentially deadly chemical that can exist in various forms Cyanide can be a colorless gas, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl), or a crystal form such as sodium cyanide (NaCN) or potassium cyanide (KCN).

Cyanide process is also called as Macarthur-forest Process It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide This process was introduced in the year 1887 by the Scottish chemists naming Robert W Forrest, John S MacArthur, and William Forrest.
