Gold Plating an overview ScienceDirect Topics

Gold is added as potassium gold cyanide, and some free potassium cyanide and carbonate exists. Phosphates and hydroxides can be added to improve conductance. When gold content is 8 g l −1 or more, the cathodic current efficiency is almost 100%, but often gold content is kept lower due to the drag-out losses. The bath is quite sensitive for organic impurities, and a frequent active carbon

Potassium dicyanoaurate Wikipedia

Potassium dicyanoaurate, also potassium dicyanoaurate(I), potassium gold cyanide, potassium gold dicyanide or gold potassium cyanide, is an inorganic compound with formula K[Au(CN)2]. It is a colorless to white crystalline powder, usually prepared by dissolving metallic gold in aqueous solution of potassium cyanide. It is most often used in gold plating applications. It contains 68.2 wt.% of gold. It is soluble in water and slightly soluble in alcohol.
