Gold cyanidation - Wikipedia
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and
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;
