What Is the Percolation Leaching Process? Xinhai

Taking the gold mine as the example, the heap leaching process is to mix the sticky ore grain with protective alkali (lime), and pile up on the leak-free ground (leaching pad), the cyanide or eco-friendly gold leaching is aspersed on ore heap. When the solution permeates the ore heap from top to bottom slowly, the gold is dissolved, and the

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.
