Heap Leaching an overview ScienceDirect Topics
The lixiviant is generally at ambient temperature. In cold regions it may be heated to enhance the kinetics of Cu extraction (Riekkola-Vanhanen, 2007; Salomon-de-Friedberg, 2000). The leaching reactions are exothermic, so the heap will increase marginally in temperature as the leach liquor percolates through the heap.

Gold Heap Leaching Process
Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement
