Potassium cyanide

Potassium cyanide (CAS 151-50-8 ), commonly referenced as KCN in industrial procurement, is an inorganic salt used primarily as a complexing and leaching agent in metal processing and surface finishing operations. Its ability to form stable metal-cyanide complexes drives its demand across electroplating and precious metal recovery sectors. In electroplating, KCN functions as the primary electrolyte carrier for depositing gold and silver. It is also used for copper and zinc coatings onto metal substrates, producing uniform, adherent finishes for electronics connectors and decorative hardware. Precious metal mining operations rely on cyanide leaching processes. In these processes, KCN solubilizes gold and silver from low-grade ores, enabling cost-effective recovery at scale. In electronics manufacturing, it supports selective metal deposition on printed circuit boards. It is also utilized for semiconductor components where precise surface conductivity is required. Jewelry finishing operations also use KCN-based baths for bright gold and silver plating on consumer goods. Potassium cyanide is supplied as white granules or lumps, with solution forms available for specific industrial applications. Standard commercial grades are offered at 98% minimum purity for industrial use. Technical grade is the predominant specification in mining and electroplating supply chains. Packaging and handling requirements are subject to strict regulatory controls and safety protocols. Procurement typically requires end-use documentation and licensed handling facilities to ensure compliance. This ensures the material is managed safely throughout the entire global chemical supply chain. Contact us for supply of Potassium cyanide Request Quote
