Bioleaching provides an alternative to more traditional physical-chemical methods. Bioleaching, also known as Bacterial oxidation technology, is the process of using bacteria to dissolved metal instead of chemical solution. Bioleaching produces less pollution and little damage to geological formation, since the bacteria occur there naturally.
