Cyanide Regeneration Processes and Methods

Cyanide Regeneration Process. Each charge of solution required from 7½ to 14 lb. per ton. The agitator, from which an unpleasant odor arose, was then stopped, and the cuprous cyanide precipitate allowed to settle for 1½ hr. The clear liquor, charged with hydrogen cyanide, was decanted into a 50ton Dorr agitator.
