Introduction Heap leaching (HL) is a flexible and low investment for gold ore processing method which is 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 gold processing method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid.
