Heap leaching a stack of gold - MiningFeeds
2018-4-25 Heap leaching is not that popular in South Africa because it is more applicable to shallow opencast mining, and South African gold mines are mostly underground operations. The method is, however, being used on a large scale in the copper mines of South America and, according to Bundo, it will be used more and more on the African continent in future.

Heap Leaching - an overview ScienceDirect Topics
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.
