Heap leaching (HL) is a flexible and economic gold ore processing method 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 …
These processes can be attractive for use on low-grade gold ores that are too expensive to process using conventional processes, and for ores that contain impurities which, in turn, contaminate conventional processing equipment (e.g. arsenic in gold ore).
