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.
