Producing Copper Nature's Way: Bioleaching

Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore. While chalcopyrite remains refractory to ambient temperature bioleaching, other copper sulfide minerals - the secondary sulfide minerals - such as chalcocite, covellite, bornite, etc. - are leachable by today's technology.

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 ...
