Use in Mining | International Cyanide Management Code .

However, in practice the amount of cyanide used in leach solutions is dictated by the presence of other cyanide consumers, and the need to increase the rate of leaching to acceptable levels. Typical cyanide concentrations used in practice range from 300 to 500 mg/l (0.03 to 0.05% as NaCN ) depending on the mineralogy of the ore.
