摘要： A process for the heap leaching of multiple ores, the process characterized by the process steps of: (i) the agglomeration or wetting of an ore feed; (ii) exposing the agglomerated or wetted ore to an inoculum containing one or more bacterial species capable of biooxidizing sulphide minerals in that ore; (iii) forming one or more heaps from the ore of step (ii); (iv) dispersing further bacterial inoculum over at least a portion of the or each heap; and (v) recovering leach solution draining from the heap and passing a portion thereof to a means for metal recovery.

摘要： A method for the bacterially assisted heap leaching of chalcopyrite includes providing a chalcopyrite containing ore heap to oxidize sulphide minerals therein, the heap containing and/or being inoculated with a sulphide oxidizing bacterial culture that either does not oxidize ferrous to ferric, or is inefficient at doing so. At least a first leach solution pond (or other suitable container) is provided, from which feed solution is fed to the heap, and which receives leach solution from the heap. A portion of the leach solution is bled and passed to metals recovery.
