US20100058894A1 Methods and systems for leaching a metal

A system and method for recovering a metal value from a metal bearing ore material are provided. A metal bearing ore can be mixed with certain substances and to form an agglomerated ore. In an intermediate state, between agglomeration and heap formation, bacteria can be added to the metal bearing ore material to produce an augmented ore.
