In 1988, Cyanco (under the ownership of Mining Services International – MSI) undertook to build a liquid sodium cyanide plant in Winnemucca, Nevada, in the heart of gold mining country. Until this time, producers of sodium cyanide made a liquid product nearer to the raw materials, which was usually thousands of miles from where the mines were.
Sodium cyanide CAS No: 143-33-9. The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) has assessed the environmental risks of sodium cyanide and made recommendations for reducing the risks from its transport and use in mining. The final report is available on the NICNAS website.
