    The effect of sulfide minerals on the leaching of gold in

    For gold leaching in the presence of sulfide minerals, there are two major mechanisms by which the sulfide can impact on the gold leaching rate (a) through the galvanic interaction between gold and the conducting mineral in contact with gold and (b) through the dissolution of the mineral which impacts on the solution speciation.
