Electrochemical bioleaching of high grade chalcopyrite

It is believed that the high lattice energy of chalcopyrite and its low solubility in such solutions are responsible for the low copper dissolution. Comparison of ORP variation with related copper recoveries (Fig. 3, Fig. 5) indicates a relationship between ORP and metal dissolution, which confirms the results of other investigations in which is reported that the dissolution rate of chalcopyrite and also the formation
