About 90% Zn was leached in a H 2 SO 4 solution at 80 °C, while the recovery of Pb was possible only in the brine leaching step. Ye et al. [22] extracted zinc and lead from lead–zinc mine tailings by the combined sequen-tial bioleaching and brine leaching. About 98% of Zn was extracted by bioleaching, and 99% of Pb was extracted in a
