Abstract
The predominant method for
gold extraction involves cyanidation
of ore under aerated conditions
to form aurocyanide
([Au(CN)2]-). Since the major reagent
cost in this process is that of sodium
cyanide, any components ("cyanicides")
apart from gold that consume cyanide
increase the cost of gold recovery. The
two most important cyanicides are sulfide-
and copper-bearing minerals. The
major products of these secondary
cyanidation reactions are thiocyanate,
the Cu1-cyanide complexes, cyanate
(from the oxidation of cyanide, especially
during the reduction of soluble
Cu11 minerals), [Fe(CN)6l4- and other
metal-cyanide complexes.
