Heap leaching is the most important method of hydrometallurgical copper extraction. Copper-containing ore material (which may be agglomerated) is built into flat-topped heaps, typically ~7 m high and having a surface area of 0.01–1 km 2. The H 2 SO 4 -containing lixiviant is applied to the surface of the heap.
