Gold and Silver Leaching by Cyanidation

Introduction to Gold and Silver Leaching. 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.
