· Under typical gold cyanidation conditions, Cu (CN) 3 2has been shown to be the dominant species from the Eh–pH diagram for the copper–cyanide–water system (OsseoAsare et al., 1984, Lu et al., 2002a).However, in the presence of hypersaline waters, as typically found in the Eastern Goldfields of Western Australia, it has been shown by Lukey et al. (1999) that the predominant .
A gold electrode should be used to ensure accurate measurement of ORP in cyanide solutions. When the potential is near or under 200 mV during the cyanide oxidation process, a platinum electrode produces a alytic reaction that causes hydrogen to form on the electrode surface. This generates potential and affects measured values.
