Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.

Metal ores are a finite resource which are in limited supply.New methods of copper extraction exploit waste ores and low grade ores.; Phytomining involves growing plants on top of low grade ores.The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions.These ions are leached from the ash using sulfuric acid.
Bioleaching microbes interact with the metal-containing material by direct contact or by affecting the water-solution holding the metal-containing material. Non-contact leaching: Free microbes produce the leaching chemicals Fe 3+ and H +. Contact leaching: Attached microbes produce the leaching chemicals Fe 3+ and H +. Cooperative leaching
