    Patent number: 4417963
    Abstract: A process for removing cyanide ions from a cyanide-containing solution by anodic oxidation. The solution is adjusted to a pH of at least about 11 and to a halide content at least equivalent to the cyanide concentration. Electrolysis is performed using intense agitation of the electrolyte to result in deposition of solid carbon on the anode.
