Inquire NowBACKGROUND NOTE ON CYANIDE IN GOLD 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.
