摘要：
The present invention concerns a decontamination process. More specifically, the present invention concerns a process for treating a soil contaminated by organic non-hydrocarbon water insoluble pollutants, comprising the concentration of said pollutants in a fraction of "fine particles" of soil and the separation of the latter from the other fractions of soil. The aforementioned fraction of "fine particles" of the soil in which the organic non-hydrocarbon water insoluble pollutants are concentrated, which is lower than the quantity of soil treated, may be decontaminated through further appropriate treatments or sent for safe disposal. The process according to the present invention also differs due to the fact that no liquid contaminants are produced to be subjected to decontamination treatment prior to recycling or release into the environment.
