Abstract
The article discusses four alternative cyanide substitutes for the recovery of gold from ores and concentrates. Cyanide has been the premier gold leach reagent for over 100 years due to its high recovery, low cost and reliability. However, environmental damage from improper management has led to widespread research aimed at identifying and developing less toxic leaching agents. The article discusses the most widely researched cyanide substitutes, but it is clear that none of them has yet made any significant incursion into the dominance of cyanide as the preferred reagent in the vast majority of gold mines around the world
