The process does not preferentially attack thiocyanate, with generally less than 10% oxidised in the process (1). Inefficiency in the process results from the direct oxidation of sulfite rather than cyanide: 2-2 4 2-3 + O →2SO (3) The sulfite process and reaction chemistry is not straight forward as indicated by the difficulties
