Gold cyanidation - Wikipedia

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. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.

Flotation reagents | Quality products, specialist advice. - Redox

Froth flotation is a method of separating minerals from gangue by exploiting differences in hydrophobicity. Wetting agents and surfactants are used to make the hydrophobic distinctions between valuable material and waste gangue possible. The selective separation of the minerals makes processing mixed ores a more economically feasible task.
