· Heap leaching process has low production cost and it can be put into production quickly. In addition, the scale of heap leaching is more flexible, even more than tens of thousands of tons. Heap leaching or granulated heap leaching can be adopted after the ore is crushed to a certain size.
Heap Leaching. Heap leaching requires the preparation of the ore, primarily size reduction, so as to maximize mineral–lixiviant interaction and the laying of an impermeable base to prevent lixiviant loss and pollution of water bodies.
