Recovering Cyanide From Gold Plant Tailings

The ability to recover cyanide from gold plant tailings has been known almost as long as the cyanidation process has been practiced, but there has been little incentive to process tailings in this way in the past. With. the development of technologies that make it possible to recover and recycle free or complexed cyanide
