Moderate permeability enhanced microbial community turnover and copper
Then, the copper extraction rate decreased slightly, but it was up to 81 % at the end of bioleaching. However, the copper extraction in the G2 group kept a slowly growing tide, with an average daily leaching rate of about 0.5 %, resulting in significant lower of copper recovery yield compared with that in the G1 group after day 35.
