The primary production of Pb via the sinter plant-blast furnace method resulted in a large number of Pb and other phases, reflecting the complex reactions occurring within each of the processes. Optical microscopy and X-ray diffraction (XRD) techniques have been used to characterize fugitive emissions and dusts generated during sintering, smelting, Cu drossing, refining, and slag fuming at a primary Pb-Zn smelter. The results displayed a complex array of phases, with the mineralogy of the dusts and fume reflecting conditions of the particular metallurgical operation. The principal Pb species followed a transformation from PbS through PbSO4 and PbO to Pb(o) (metal) from raw materials to the refinery. The fugitive emissions generated by the blast furnace were of a finer size with more complex chemistry than fugitive material from other source areas. XRD identified a mixture of PbS, ZnO, and ZnS, associated with one or more of the Cl-bearing phases Pb(OH)Cl, PbCl2, Pb4O3Cl2, Na3Pb2(SO4)3Cl, Pb10(SO4)Cl2O8, Pb4SCl6, and Pb7S2Cl10. The presence of Cl-bearing phases in the fume has possible health implications.
通过烧结厂 - 鼓风炉法初级生产铅会产生大量的铅及其他物相，这反映了每个工艺过程中发生的复杂反应。光学显微镜和X射线衍射（XRD）技术已被用于表征一家铅锌冶炼厂在烧结、熔炼、铜浮渣处理、精炼和造锍吹炼过程中产生的无组织排放物和粉尘。结果显示出一系列复杂的物相，粉尘和烟尘的矿物学反映了特定冶金操作的条件。主要的铅物种从原材料到精炼厂经历了从硫化铅通过硫酸铅和氧化铅到金属铅（Pb(o)）的转变。鼓风炉产生的无组织排放物颗粒更细，化学组成更复杂，比其他来源区域的无组织排放物更复杂。XRD鉴定出硫化铅、氧化锌和硫化锌的混合物，与一种或多种含氯物相相关，这些含氯物相包括碱式氯化铅（Pb(OH)Cl）、氯化铅（PbCl2）、氯氧化铅（Pb4O3Cl2）、钠铅复盐（Na3Pb2(SO4)3Cl）、氯铅矾（Pb10(SO4)Cl2O8）、硫氯铅矿（Pb4SCl6）和十氯二硫化七铅（Pb7S2Cl10）。烟尘中含氯物相的存在可能对健康有影响。
