| 520 | 3 |a"A literature search was made to determine whether ozonation would be technically and economically attractive for the treatment of cyanide-bearing gold mill effluents. The publications covered in this survey were those concerned with (1) recent advances in ozone generation and gas-liquid contacting devices of interest to cyanide oxidation, (2) conditions for a rapid and complete decomposition by ozone of both simple and complex cyanides commonly found in gold mine effluents and (3) cost of ozonation under these conditions. This state-of-the-art review shows that ozonation might be a valid alternative to conventional methods of cyanide detoxification of gold mill effluents. The ozonation process at the time of writing is relatively high in capital cost but low in operating cost compared with conventional processes"--Abstract, p. i. |
