copper extraction can be achieved even when the ORP was beyond the proposed region. Later, they investigated the selecting bioleaching of mixed ores of chalcopyrite and marmatite using silver-containing waste [13]. Marmatite was antecedently dissolved, and the electrochemical interactions between these two minerals have improved marmatite dissolution. Silver was believed to have changed......
