Sodium cyanide (NaCN) is widely used in gold mining for its ability to efficiently extract gold from ores. It forms a water-soluble complex with gold, allowing for the separation and recovery of gold from ore through the cyanidation process. Despite its effectiveness, sodium cyanide is highly toxic and requires careful handling and management to prevent environmental contamination and ensure worker safety.
