The leaching is practised in large basins containing up to 12 000 tons of ore. The procedure is similar to that of dump leaching. In some heap leaching operations, pipes are placed in strategic positions within the heaps during its construction to provide the deeper portions of the heap with sufficient amounts of oxygen. 5.2.3 Underground leaching

Heap leaching

Oct 28, 2015· Not unlike in-situ leach mining, heap leach mining is a process whereby Uranium, Copper and other precious metals are extracted from ore with a chemical solution. Ore is mined, crushed and dumped onto a "leaching pad" made from impermeable membrane with a minimum thickness of 1.5mm, often on a bed of clay.
