Gold Heap Leaching Process XinhaiHeap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.
