The acid consumption for the current secondary sulfide heap bioleach operation was reported to be between 13.5 and 28.6 kg/ton of ore depending on the ore particle size, acid injection flow rate lit/m 2.hr and ore mineralogy. In this study, the net acid consumption was chosen for an average of 20 kg/ton for a low-grade chalcopyrite ore.
