Sodium cyanide industrial use is maily in gold mining. Sodium cyanide (NaCN) is a chemical used overseas predominantly in metal plating and chemical applications such as dyes and pharmaceuticals. In Australia it is principally used for the gold mining industry to extract gold from gold bearing ore using the carbon-in-leach and carbon-in-pulp processes with 98 per cent of Australia’s gold production dependent on it. These processes enable commercial recovery of gold at very low concentrations (down to just 0.85gm per tonne or 0.85 ppm of soil or mine tailings). Between 300 and 500 tonnes of sodium cyanide (valued at ca. US$0.7m) is required for each tonne of gold (valued at say $13m) produced so that cyanide represents around 8 per cent of the value of gold produced. Sodium cyanide is also used in nickel production as an arsenic suppressant. itcilo.it Of course there is way to know what North Korea would plan to do with the chemical, but they do have a substantial gold and nickle industry. minerals.er.usgs.gov
