Cyanidation is the predominant process for the extraction of precious metals from their ores. However, given the toxic nature of cyanide, effluents from processing plants must be properly treated to avoid environmental damage. The present work shows a thermodynamic simulation for the identification of predominant species from the oxidation of free cyanide (i.e., HCN and CNˉ) and weak cyanide complexes (i.e., Ag(CN) 2 ˉ ) by employing hydrogen peroxide (i.e., H 2 O 2 ) at different concentrations (i.e., 1.4×10 -2 , 2.1×10 -2 , and 2.8×10 -2 M).
