Cyanide Destruction Plants operate by introducing a reactant that oxidizes the cyanide ions in solution in gold processing plant tailings. The reaction that takes place converts the cyanide into a complex or form that is non-toxic achieving effective cyanide detoxification.
contact usThe cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve ...

contact usCyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore. Cyanide gas is used to exterminate pests and vermin in ships and buildings. If accidentally swallowed, chemicals found in acetonitrile-based products that are used to remove artificial nails can produce cyanide when metabolized by the body.
contact us· The use of cyanide for gold extraction is a relatively efficient process.14,15 While cyanide has been commonly used by large scale gold miners, this technology is now popular and is being used in the SGM industry worldwide.8,14–16 This is the case in northern Tanzania, including the Lake Victoria basin, where cyanide is used to leach the gold ...
