    History of The Cyanide Leach ProcessStudy AreaMethodsResults and DiscussionPore Water BehaviorSummary and ConclusionsThe evolution of cyanidation technology in the pursuit of precious metals dates back 200 years. In 1793 potassium cyanide was recognized as a gold solvent (Hiskey 1985). In 1844 Elsner investigated the reactions of various metals in a potassium cyanide solution discovering that gold dissolution took place only in the presence of dissolved oxygen (Bosqui 1899). This dissolution reaction known as Elsners Equation is written as:4 Au See more on
