• COPPER EXTRACTION BY BIO-LEACHING OF FLOTATION COPPER SULPHIDE

    The bio-leaching, or bio-assisted leaching, can be defined as a natural dissolution process of sulphide minerals, as a result of the oxidation of those minerals through bacteria releasing the metals of interest in their soluble ionic forms (Rojas, 1998).
