Description

Sodium Cyanide CAS NO 143-33-9 is a highly reactive inorganic salt with the chemical formula NaCN. This compound is a critical industrial reagent valued for its strong affinity for metals, making it indispensable in extraction and surface treatment processes. It is primarily required by the mining industry for gold and silver extraction, as well as by electroplating and chemical synthesis sectors.

Application

• Gold and Silver Ore Extraction: The primary global application, used in the cyanidation process to leach precious metals from ores.
• Electroplating: Acts as a complexing agent in baths for electroplating metals such as gold, silver, copper, and zinc.
• Chemical Synthesis: Serves as a key precursor in the manufacture of various chemicals, including cyanuric chloride, cyanogen chloride, and certain pharmaceuticals and dyes.
• Metal Cleaning and Hardening: Used in case-hardening processes for steel and for cleaning metal surfaces.
• Fumigation: Historically used in pest control, though this application is now highly restricted and regulated.
• Laboratory Reagent: Employed in analytical chemistry and research as a source of cyanide ions.

Quality Control

Our Sodium Cyanide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity and impurity profiles, typical for industrial and mining grades. A Certificate of Analysis (COA) detailing assay, moisture content, and key impurity levels is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area, away from acids, oxidizing agents, and moisture. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed. Store separately from food and feedstuffs. Observe all local and international regulations for hazardous materials.
