Introduction: Cyanidation is a hydrometallurgical process used to extract gold and silver from low grade ores by converting them to water soluble metal cyanide complexes for recovery by precipitation on zinc dust, activated carbon, or ion exchange resins. Measurement and control of cyanide concentration has a major impact on process efficiency and operating cost. Accurately measuring cyanide available for leaching ores containing copper and metallic sulfides is problematic. Titration methods commonly used for process control in gold leaching poorly estimate the amount of cyanide when copper is present. Oth
