heap leaching for tin ore high performance

4 Factors Influence the Effect of Heap Leaching Method

The ore with good permeability can be piled higher. 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.

Heap Leaching an overview ScienceDirect Topics

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
