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 theore grades and rapidly increasing costs (Goldsheet Mining Directory) Cyanidation is the process that accounts for more than 80% of worldwide gold production, with the balance (< 20%) recovered either as a byproduct of processing copper/gold flotation concentrates or by direct smelting of highgrade gravity concentratesHighlights of the Past Five Decades of Gold Ore Processing in
