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.

What is Heap Leaching? (with picture)

2021-2-17  The heap leaching process is used to extract metals such as gold, copper, and nickel and may be used on low grade ores and mining tailings which are generally considered to be of no commercial value. The process also produces yellowcake, a concentrate leached from uranium ore used in the production of nuclear reactor fuel.
