  • Cyanide Wikipedia

    Cyanide is mainly produced for the mining of gold and silver: It helps dissolve these metals and their ores. In the cyanide process finely ground highgrade ore is mixed with the cyanide (concentration of about two kilogram NaCN per tonne) lowgrade ores are stacked into heaps and sprayed with a cyanide solution (concentration of about one kilogram NaCN per ton).

  • Gold cyanidation Wikipedia

    Gold cyanidation is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold copper zinc and silver represents approximately 13% of cyanide consumption globally with the remaining 87% of cyanide used in other industrial processes such as plastics adhesives

  • The Chemistry of Cyanide Poisoning and Why it Kills

    Sodium cyanide (NaCN) potassium cyanide (KCN) hydrogen cyanide (HCN) and cyanogen chloride (CNCl) are lethal but thousands of compounds called nitriles contain the cyanide group yet aren't as toxic. In fact you can find cyanide in nitriles used as pharmaceuticals such as citalopram (Celexa) and cimetidine (Tagamet).

  • Cyanide Use in Gold Mining Earthworks

    Cyanide can mean any one of various compounds containing the chemical group CN: one atom of carbon (C) and one atom of nitrogen (N). Because it is organic it reacts readily with living organisms. Cyanide easily combines with many metals making it useful in separating metals like gold from their ore. How is cyanide used in mining?
