Abstract

Abstract

The study takes a Pb contaminated soil around a smelter in Henan Province as the object. ICP, XRD, EDS, SEM, and other analysis methods were conducted based on process mineralogy. The study results shows that the lead of the soil exists mainly in form of PbCO₃, Pb₅(PO₄)₃Cl₂ and PbSO₄, it also contains a small amount of PbS. The microstructure of soil exhibits that the soil particles adhere to each other as flocculent aggregates, the interface between particles is not clear, and the surface of each particle is dirty. The cubic galena and orthorhombic or massive cerussite are occasionally found in the samples, besides, the Pb is also distributed in siderite and limonite. In this study, a new idea of applying material separation technology to remediation of heavy metal contaminated soil is put forward.
