Description
Sodium Cyanide for Mining, Chemical Manufacturing, and Laboratory Use
Sodium Cyanide (CAS No. 143-33-9) is a highly soluble, white granular inorganic compound known for its strong affinity with precious metals. Offered in 95% and 97% purity, this product is available in AR (Analytical Reagent) and LAB grade, making it suitable for demanding industrial applications and laboratory processes.
Sodium Cyanide is most notably used in gold and silver extraction, where it forms water-soluble metal complexes through leaching. It is also employed in electroplating, chemical synthesis, and as a reagent in the production of nitriles and other organic intermediates.
Due to its high toxicity and reactivity, Sodium Cyanide must be handled only by trained personnel in regulated environments. It should be stored in dry, airtight containers made of corrosion-resistant material to ensure safety and maintain stability for up to 5 years.
