Yes ! It is. Many people died in pursuit of unraveling the taste of KCN-also known as Potassium Cyanide. KCN is an interesting chemical compound,which is actually a poison. 300 mcg of Cyanide is enough to cause death in a few milli seconds.
Then, opening the clip, run through more cyanide solution and then water, so as to wash the gold-carrying liquor thoroughly into the beaker. There is no hot water, no sterilising, no cyanide gauze even, but iodine saves many lives, and we have plenty of it.

Cyanide is a poison has a high toxicity level. The threshold or lethal dose of a person inhaling or ingesting cyanide is very, very low. This means that with very low cyanide concentrations a person may experience poisoning and even death.
Cyanide poisoning is a form of histotoxic hypoxia because the cells of an organism are unable to create ATP, primarily through the inhibition of the mitochondrial enzyme cytochrome c oxidase. Cyanide is quickly metabolized to 2-amino-2-thiazoline-4-carboxylic acid and thiocyanate with a half life of 10–30 minutes as a detoxifying mechanism.

Using the amalgamation technique with cyanide, the gold content that can be obtained can reach 89-95% much better than other methods that only reach 40-50%. But after war broke out, the cyanide was transferred to its function as a dangerous chemical. Cyanide begins to be applied to genocide and suicidal poison. Another use of this cyanide is to kill rats, chikes and rats to protect food crops.

Cyanide is a carbon-nitrogen chemical unit which combines with many organic and inorganic compounds. The most commonly used form, hydrogen cyanide, is mainly used to make the compounds needed to make nylon and other synthetic fibers and resins.
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 .
