Heap Leachingan overviewScienceDirect Topics

2.1 Leaching. Most copper leaching is done by piling broken ore 0.5% Cu into flatsurface, 310m 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 15kg Cum 3.
