The PSD shows the problem in attempting to produce lead in a single step. The volatility of PbS and PbO make it desirable to keep the gas volume as low as possible (i.e., use pure O 2 in smelting). But this means operating along the pSO 2 =1 isobar, thus producing a large amount of PbO-containing slag in order to produce a low-sulfur …
