Electroplating that uses cyanide in the plating bath which

The cyanide in the bath is a major bath constituent and not an additive. However, the self-regulating chemistry of the bath causes the bath to act as if wetting agents/fume suppressants are being used and to ensure an optimum plating process. All cyanide plating baths at pH greater than or equal to 12 have cyanide-metal complexes in solution.
