In the interests of the environment, gold plants voluntarily prescribe to the International Cyanide Management Code (visit www.cyanidecode.org for further information). The objective of the Code is to improve the management of cyanide used in gold mining and to

Cyanide gold processes can be divided into stirring cyanide and percolation cyanide. Stirring cyanide is used to process tailings or complement full mud cyanidation after gravity, mercury mixing and flotation of gold concentrates. Percolation cyanide is used to treat flotation tailings and heap leaching of low-grade gold ore.
