Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, andpounds from ore using a series of chemical reactions that absorb specific minerals and re separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
