Pbso4 phase

SpletThis ‘living’ organism exists due to the simultaneous operation of two electrochemical systems: the lead system (Pb/PbSO4 and PbO2/ PbSO4) and the water system (H2O/H2 and H2O/O2). The latter is thermodynamically supported, but kinetically suppressed. Splet04. jan. 2024 · Kirkwood and Nutting investigated the oxidation of galena crystals in air below 200° and 350° C and determined that PbSO4 is the first product to form followed by PbO·PbSO4 and 4PbO·PbSO4. Studies on lead sulfide roasting confirm that the roast reduction process should be an ideal method for recovering lead from lead sulfide.
