Cyanide Use in Gold Mining Earthworks
Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. 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;Cyanide Waihi Gold,This is not surprising, given the less desirable aspects of its historical use, and the many myths and misconceptions relating to cyanide.
