Use in Mining International Cyanide Management Code

Gold and silver typically occur at very low concentrations in ores less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous chemical (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore. Typical hydrometallurgical recovery involves a leaching step during which the metal is dissolved in an
