Heap leaching Wikipedia

Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re separates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it.
