Product information
Sodium cyanide is the sodium salt of hydrogen cyanide. PubChem confirms CAS 143-33-9, formula NaCN and a molecular weight of approximately 49.01 g/mol. It is an acutely toxic chemical requiring tightly controlled industrial systems.
In mining, sodium cyanide is used in established hydrometallurgical extraction processes for certain precious-metal ores. Because commercial briquettes, pellets and solutions differ in assay, moisture and handling requirements, Hamara’s stated 98% briquette product should be confirmed from the manufacturer’s TDS and SDS before publication.

General guidance
Handling and storage
Sodium cyanide is acutely toxic and requires rigorous closed handling, segregation and exposure controls under the current SDS and applicable regulations. It must be protected from acids because acid contact can release highly toxic hydrogen cyanide. Storage, emergency arrangements and protective equipment must follow the exact supplier SDS and local regulatory requirements.
Applications
