Gold and Silver Leaching by Cyanidation
The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890. From there it spread to Australia, …

Cyanide Consumers in Gold Leaching Process
The presence of stibnite, realgar and orpiment is a problem due to react with cyanide at pH values higher than 10. These minerals are oxygen and cyanide consumers and the products formed during the reaction with cyanide may passivate the surface of gold and retard its dissolution. Carbon can be present as carbonate mineral and inorganic material.

Cyanide Use in Gold Mining
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;
