Typical cyanide concentrations used in practice range from 300 to 500 mgl 0.03 to 0.05 as NaCN depending on the mineralogy of the ore. The gold is recovered by means of either heap leaching or agitated pulp leaching. In heap or dump leaching the ore or agglomerated fine ore is stacked in heaps on a pad lined with an impermeable membrane.
