UsedGold Extraction: One of the most common applications of sodium cyanid is in the extraction of gold from its ores. It forms a complex with gold ions, known as sodium auricyanid or gold cyanid, which is soluble in water.

Metal Plating: Sodium cyanid is used in electroplating processes, particularly for the deposition of silver and gold onto base metals. It acts as a source of cyanid ions in the electrolytic solution, facilitating the transfer of metal ions from the anode to the cathode.

Organic Synthesis: In organic chemistry, sodium cyanid serves as a precursor in the synthesis of various organic compounds, including nitriles and cyanohydrins. These compounds find applications in the production of pharmaceuticals, pesticides, and other chemicals.

Fumigation: Despite its toxicity, sodium cyanid is sometimes used in fumigation to control pests, especially in enclosed spaces such as warehouses or shipping containers.

Chemical Intermediates: Sodium cyanid is a versatile chemical intermediate in the synthesis of other compounds, such as cyanuric chloride, which is used in the production of herbicides and pesticides.

Dyeing Industry: Sodium cyanid is employed in the dyeing industry as a dye fixative or as a component in certain dye formulations.

Case Hardening: In metallurgy, sodium cyanid is used in case hardening processes to increase the surface hardness of steel components.

Analytical Chemistry: Sodium cyanid is used in analytical chemistry for the detection of metal ions.
