Gold Cyanidation Ground Truth Trekking

Cyanide (CN), a single carbon atom triplebonded 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 quot;gold cyanidationquot;, quot;the cyanide processquot;, or quot;cyanide leach miningquot;, cyanide is used to extract gold from the surrounding rock. While cyanide is both effective and economical, its use and transportation present significant environmenta
