Selective reduction of PbSO4 to PbS with carbon and flotation treatment of synthetic galena
2015
In order to recover lead from the zinc leaching residues, a new technology involving selective reduction of lead sulfate to lead sulfide with carbon followed by flotation was investigated. The reduction thermodynamics of PbSO 4 was discussed and the effects of molar ratio of C to PbSO 4 , reaction temperature and time were examined by thermogravimetry (TG) and XRD. Verification tests were further carried out to prove the conclusions of thermodynamic and TG analyses, and the transformation
