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.
Gold and silver typically occur at very low concentrations in ores - less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous chemical (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore. from the ore.
Traditionally, gold mining has depended on harsh chemicals such as cyanide and mercury to extract gold from ore. This has left our planet with a legacy of toxic waste which is harmful to health and the environment. For over 50 years, the industry and leading research institutions have been trying to find such an alternative without much success.
