In other words, the positive effect of ASM on copper leaching rate could manifest itself under a lower potential (Buckley and Woods, 1984, Dutrizac, 1990). To obtain a higher copper leaching rate at early leaching stage, removing the sulfur of ASM at lower potential was thought as a good technological method (Zhao et al., 2019).
