Advances in the Cyanidation of Gold - ScienceDirect

Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat low-grade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of various interferences.
