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 to the ...
A diagram illustrating open cast and shaft mining is shown in Figure 14.3. Figure 14.3: Diagram showing open pit and shaft mining. Processing the gold ore (ESBRM) For every ton of ore that is mined, only a very small amount (about (text{5}) (text{g})) of gold is extracted.
