4 Factors Influence the Effect of Heap Leaching Method

For the ore with poor permeability, the height of ore heap should not be too high, otherwise the permeability of ore heap will be reduced and the leaching time will be prolonged. Generally speaking, it is advisable to keep the height of ore pile at 3~10 meters. The height of the ore pile can be determined by mineral processing test. Conclusion
