Free cyanide

A free cyanide electroplating bath is a special form of electrolyte bath used in electroplating to coat metallic surfaces. In this context, "free cyanide" refers to the presence of cyanide ions in the electrolyte, which play an important role in the electroplating processes.

The use of cyanide in electroplating baths is widespread due to its ability to form stable metal-cyanide complexes. These complexes facilitate the deposition of the metal on the substrate to be plated and help to produce smooth and uniform coatings.

The free cyanide electroplating bath is often used for coating metallic workpieces with precious metals such as gold or silver. These precious metals are used in the electrical industry, jewelry manufacturing and other precision applications. The use of free cyanide enables precise control of the electroplating processes and helps to produce high quality, adhesive and corrosion resistant coatings.

However, it is important to emphasize that the use of cyanide in electroplating processes is controversial due to its toxicity and associated risks to health and the environment. Therefore, strict safety measures and environmental regulations are necessary to ensure the safe handling of free cyanide in electroplating baths. The industry is constantly working to develop alternative processes that are less harmful to the environment in order to reduce the use of cyanide.
