    SummaryProcessEnvironmental ConcernsGold Cyanidation in AlaskaReferencesCyanide (CN), a single carbon atom triple-bonded to a nitrogen atom, has proved extremely useful in extracting gold from ore. However, with a toxic reputation dating back to the Holocaust, its use in mining has been very controversial. Through a process called "gold cyanidation", "the cyanide process", or "cyanide leach mining", cyanide is used to extract gold from the surrounding rock. While cyanide is both effective and economical, its use and transportation present significant environmental risks.
