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.
