Cyanide Use in Gold Mining Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

Destruction of cyanide in gold mill effluents: biological

2003-9-1  Cyanide is used in the production of organic chemicals such as nitrile, nylon, and acrylic plastics. Other industrial applications of cyanide include electroplating, metal processing, steel hardening, photographic applications, and synthetic rubber production. Gold mining operations use dilute solutions of sodium cyanide (100–500 ppm).
