4 Factors Influence the Effect of Heap Leaching Method - Mining-pedia

In practice, the ore particles that have been crushed to 5~20 mm are sent to heap leached. If the content of ore fines -200 mesh exceeds 35%, the conventional heap leaching method will cause the surface of the ore heap to form a groove flow, thus reducing the leaching rate of gold. 2.

Heap leaching - Wikipedia

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 ...
