Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds 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 ,...
