Gold Cyanidation Process In Stirred Vessel

gold cyanidation process in stirred vessel

01.06.2016 A reaction between gold and cyanide solution in the presence of oxygen leads to the extraction of gold from its ore during gold cyanidation process. Since excellent mixing and high contact area between cyanide, ore particles, and dissolved oxygen in liquid phase are required, stirred tanks are usually the type of vessels used for this process.

08/06/2016· The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.
