Gold/Silver Heap Leaching and Management Practices That ...

During gold heap leaching an alkaline pH (9 to 11) is main- tained, but afterwards the piles are usually rinsed with fresh water and the pH approaches a more neutral range; thus, much of the free cyanide can be volatilized. Leach residue near the surface of the heap can become less alkaline with the absorption of CCL from the atmosphere.
