Approaches to Cyanide Code Compliance for Tailings Storage

Wildlife mortality on cyanide bearing tailings storage facilities (TSFs) is a contentious matter (Minerals Council of Australia, 1996, Sinclair et al., 1997) that has been evident since the onset of cyanide bearing tailings disposal at gold mines (Donato, 1999).

The ratio of cyanide to copper of 3.14 to 1 indicated a possible deficiency of free cyanide for rapid leaching of gold, although the usual method of titration indicated 0.041% NaCN. The additions of cyanide to the mill solutions were, therefore, increased so that the usual method of titration indicated 0.07 to 0.09% NaCN.
