Heap Leaching an overview | ScienceDirect Topics

Leaching. Most copper leaching is done by piling broken ore (∼% Cu) into flatsurface, 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.
