    OverviewHistoryChemical reactionsApplicationRecovery of gold from cyanide solutionsCyanide remediation processesEffects on the environmentAlternatives to cyanide

    Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagentsfor mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other i
