The stability of gold deposition rate shows almost no thermal decomposition in heat idling test. Longer bath life of 12 metal turnovers (MTO) translates to lower consumption of chemicals as well as high bath stability. Too short bath life within 5 MTO is the disadvantage of existing cyanide-free immersion gold in wafer final finish process.

Gold and silver are extracted from dilute or low-grade ores containing a high percentage of impurity by a hydro metallurgical process called cyanidation. In this process, cyanide is converted to a water-soluble complex of metal-cyanide, which is then precipitated using activated carbon, zinc dust, or ion-exchange resins.

Today, approximately 15-20 per cent of the world's current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation. Ores are refractory for many reasons but commonly because gold occurs as tiny inclusions or submicroscopic gold within a sulphide mineral matrix.
