Abstract: The objective of this study was to examine the use of flying ash to remove the copper cyanide species from gold mine effluents. In order to discharge them safely with minimum impact to the environment the effluents must be treated in such a way that the legal conditions were attained with the lowest possible cost. This paper presents the treatment of cyanide solution originating from tailing ponds at the end of detoxification by direct contact with flying ash.
