Abstract
⺠Hydrothermal sulfidation-floatation was applied to treat the heavy-metal-containing sludge. ⺠72.67% of Pb and 88.74% of Zn in sludge can be converted to PbS and ZnS. ⺠Synthetic ZnS had a lower selectively floatability than PbS and CuS. ⺠The recovery of ZnS can increased to 72.8% after crystal modification in hydrothermal condition. ⺠After sulfidation-floatation treatment, the heavy metal remaining in the tailings was stable.
