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.

摘要： Contaminated soils are treated in that an aqueous slurry of the soil is separated into a coarse fraction and a fine fraction, the fine fraction is subjected to flotation, the resulting froth is dewatered and then carried away as a pollutant concentrate, and the underflow from the flotation is dewatered and is then carried away as purified soil. An emulsified oily vegetable oil is used as a collector agent for the selective flotation or an emulsified light mineral oil is used as a collector agent for the selective flotation and a light mineral oil is stirred as a conditioning agent into the fine fraction before it is subjected to the selective flotation.

摘要： A process for decontaminating a medium polluted with metals and hydrophobic organic compounds (HOC) includes providing an acidic slurry of water, acid, chloride salt, surfactant, and the polluted medium. Flotation is preformed on the acidic slurry to form a HOC-rich froth and an HOC-depleted slurry and the froth is recovered. The slurry is separated to obtain a treated solid and a liquid effluent rich in metallic ions. Preferably, the process also includes recuperating the metals by chemical precipitation and/or electrodeposition to produce a treated solution. Also provided are a decontaminant having an acid, a chloride salt, and a surfactant as well as a chemical kit for decontaminating the polluted medium including the decontaminant in which the acid, chloride salt and surfactant can be mixed with polluted medium in the presence of water before removing at least a portion of the metals and HOC from the polluted medium.

摘要： A process for cleaning contaminated soil containing a heavy metal, comprising:

(a) an extraction step where extracting the heavy metal contained in the soil as a heavy metal ion by bringing an extracting reagent into contact with the soil to obtain an extract "a" containing soil and the heavy metal ion;
(b) a solid-liquid separation step where carrying out the solid-liquid separation of the extract "a" to obtain cleaned soil and an extract "b" containing the heavy metal ion;
(c) a precipitation step where adjusting the pH of the extract "b" to 3 or more in the presence of an iron ion to precipitate the heavy metal together with ion so as to obtain an extract "c" containing iron and heavy metal precipitates; and
(d) a heavy metal recovery step where foaming the extract "c" in the presence of a surfactant and collecting the iron and heavy metal precipitates by bubbles to recover them.

The process can remove a heavy metal from the polluted soil containing the heavy metal efficiently.
