  • Gold Cyanidation Process Mineral Processing & Metallurgy

    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.Cyanide Leaching Chemistry & Gold Cyanidation,Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.

    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.Gold extraction Wikipedia,The cyanide process is the industry standard.
