Uses of Sodium Cyanide in Chemical Engineering
"Application of Sodium Cyanide"

Sodium cyanide is widely used in the field of chemical industry.

First, in metallurgy and chemical industry, sodium cyanide is often used as a leaching agent. The extraction of precious metals such as gold and silver depends on its work. The interaction of sodium cyanide solution with ores containing precious metals can make gold and silver form soluble cyanide complexes, and then through separation, reduction and other processes, pure precious metals can be obtained. This extraction method is efficient and selective, which can make full use of precious metals in ores and improve the utilization rate of mineral resources.

Second, in organic synthesis chemicals, sodium cyanide is also an important raw material. Often involved in many organic reactions, such as the preparation of nitriles. Through a specific reaction path, sodium cyanide interacts with corresponding halogenated hydrocarbons or carbonyl compounds to form nitriles. Nitrile compounds are key intermediates in organic synthesis and can be further converted into a variety of organic compounds, such as carboxylic acids, amines, etc., which are widely used in medicine, pesticides, dyes and many other fields, providing a basis for the diversification of chemical products.

Third, in electroplating chemicals, sodium cyanide can be used as an additive in electroplating solutions. In the electroplating process, the addition of an appropriate amount of sodium cyanide can improve the quality and performance of the electroplating layer. It can evenly deposit metal ions on the surface of the plated parts, resulting in a flat, dense and well-bonded coating, improving the corrosion resistance and aesthetics of the plated parts, and playing an important role in the electroplating process of electronics, machinery and other industries.

However, sodium cyanide is highly toxic. When using it, it must strictly follow the operating procedures and handle it with caution to prevent leakage and endanger life and the environment.
