heap leaching design

Much thought and design goes into the making of a heap leach to derive the best most economical solution for recovering the gold from the ore. Once the gold has been dissolved in the cyanide and the ore body has been reasonably depleted of its gold there are two main processes for recovering the gold from the pregnant cyanide solution.

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 ...
