On the other hand, due to high toxic levels, sodium cyanide is supplied either from briquettes or liquid. Moreover, since decades sodium cyanide is contributing immensely in extracting gold and other metals such as copper, silver, and zinc from ores globally. Due to toxicity levels, sodium cyanide is utilized very cautiously at industrial sites.
The gold mining industry relies on sodium cyanide extraction to recover gold. This chemical is classed as highly toxic in the environment and so mines are required to undertake rigorous control and management in terms of cyanide use on a mine site under most European and Asian jurisdictions.
