BACKGROUND NOTE ON CYANIDE IN GOLD MINING
Cyanide use in mining Gold typically occurs at very low concentrations in ores – less than 10 g/ton. The most used process for gold extraction is hydrometallurgical recovery (gold cyanidation), which involves a “leaching” step during which the gold is dissolved in an aqueous medium, followed by the separation of the gold bearing solution from the residues. Gold is one of the noble metals ...
