Copper extraction from low-grade chalcopyrite in a
The low-grade chalcopyrite contained high content of alkaline gangue, which consumed acid and led to the increase of pH. To alleviate the adverse effect of high pH on chalcopyrite bioleaching (Wang et al. 2018a), the pH was daily adjusted to 2.0 ± 0.1 before day 112 and then the adjustment frequency was changed to once every 3 days. …
