摘要： The present invention relates to the decontamination of soil and the like and, in particular, soils which are contaminated with metal as a result of the activities of human beings. The invention provides a physical and a chemical means for treating soil aggregate so as to obtain a product aggregate having a relatively low metal content. The physical means is characterized by the classification of a soil aggregate into portions of differing size and metal content. The chemical means is characterized by contacting a soil aggregate with an aqueous lixiviant comprising an organic acid component to lift metal from the aggregate. The physical and chemical means may be used in a combined process for decontaminating soil aggregate.

摘要： A process for the decontamination of a metal contaminated soil aggregate so as to obtain a product comprising a treated soil component having a metal content lower than that of the metal contaminated soil aggregate, the metal contaminated soil aggregate comprising at least one metal selected from the group comprising Pb, Hg, Cu, Cd, Zn, Ag, Ni, Co, Ga and Cr, the contaminated soil aggregate comprising a classified soil fraction representing soil particles having a size of from 0.15 mm and smaller, comprising: providing an initial aqueous soil slurry comprising the contaminated soil aggregate, admixing at least one water soluble dialkyldithiocarbamate with the initial soil slurry so as to obtain a product aqueous soil slurry comprising one or more water insoluble metal-dialkyldithiocarbamate complexes, and separating one or more of the insoluble metal-dialkylthiocarbamate complexes from the product aqueous soil slurry so as to obtain a treated product aqueous slurry comprising a treated soil component having a metal content lower than that of the metal contaminated soil aggregate, wherein the metal moiety of the one or more water insoluble metal-dialkyldithiocarbamate complexes is a member of the group comprising Pb, Hg, Cu, Cd, Zn, Ag, Ni, Co, Ga and Cr.

摘要： A process for decontaminating a metal contaminated soil aggregate wherein at least one water soluble dialkyldithiocarbamate is admixed with an initial soil slurry so as to obtain a product aqueous soil slurry comprising one or more water insoluble metal-dialkyldithiocarbamate complexes which insoluble complexes may then be physically separated from the soil slurry to leave behind a product having a metal contamination level lower than that of the initial contaminated soil.
