A method for the bacterially assisted heap leaching of chalcopyrite, themethod characterised by the steps of: providing a chalcopyrite containing oreheap to oxidise sulphide minerals therein, the heap containing and/or beinginoculated with a sulphide oxidising bacterial culture that either does notoxidise ferrous to ferric, or is inefficient at doing so; providing at least afirst leach solution pond (or other suitable container), from which feedsolution 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 formetals recovery.
