<p>A method for the bacterially assisted heap leaching of chalcopyrite, the method characterised by the steps of: providing a chalcopyrite containing or e heap to oxidise sulphide minerals therein, the heap containing and/or being inoculated with a sulphide oxidising bacterial culture that either does not oxidise ferrous to ferric, or is inefficient at doing so; providing at least a first leach solution pond (or other suitable container), from which feed solution is fed to the heap, and which receives leach solution from the heap ; andbleeding a portion of the leach solution and passing same to a means for metals recovery.</p> |
