※ Potassium Copper Cyanide is a "water soluble double salt". You do not need solvating copper cyanide in KCN solution and filtering process because our double salt is readily soluble in water and clean. You just pick up a desired amount of our double salt and simply dissolve it with water. Then it is ready to be used. It is very convenient, clean and environment friendly and cost effective; saving labor, space & fixed cost, and keeping waste less.
