Sodium Cyanide - Sodium Cyanide Solution
What is it?
Sodium Cyanide, NaCN in solution, is a clear colourless to straw coloured solution. It is a highly toxic chemical compound, also known as Sodium Salt of Hydrocyanic Acid and Cyanogran.
Where Is It Applied?
It is most commonly used as a lixiviant for the dissolution of gold and other precious metals, with 98% of Australia’s gold production dependent on it. Gold is extracted from gold bearing ore using the carbon-in-leach and carbon-in-pulp processes. These processes enable commercial recovery of gold at very low concentrations. Sodium Cyanide is also used in nickel production as an arsenic suppressant.
