Abstract

A method of continuously decontaminating a material, where said material passes a charging sluice to a closed system, is extracted counterstream by means of an extractant in an extraction section including one or more extraction pipes provided with worm conveyors, is subjected to a steam stripping in a steam stripping section for removal of the extractant, and leaves the closed system through a discharging sluice, using coreless worms for the conveying of the material, and an assembly to be used for carrying out the method in form of a closed system comprising a charging sluice, an extracting section with one or more extraction pipes provided with worm conveyors, a steam stripping section, and a discharging sluice, wherein one or more of the worm conveyors of the assembly are coreless worm conveyors. The method and the assembly according to the invention allow an efficient and continuous counterstream extraction of contaminated materials.
