This invention relates to a process for electroreclamation of soil material. A plurality of electrodes is brought into current-conducting connection with the soil material to be reclaimed. One or more of the electrodes are brought into current-conducting connection with the positive or negative pole of a source of DC voltage and the remaining electrodes are brought into contact with the other pole of the source of DC voltage. There are thus formed one or more anodes and one or more cathodes. An electric current is passed through the soil material to be reclaimed between the differently charged electrodes.
