Abstract
Proposed is a process for the treatment of stockpile material in which stockpile material is treated by means of liquids and/or gases in a stockpile material body at least essentially sealed all around; further a container for the long-term storage of stockpile material, with a casing resting on a base and a cover for the casing cavity, as well as a radial gradient drainage to the container bottom center, in which a first surface filter layer with drainage pipes and on top of this a first mineral sealing layer is disposed on the container bottom, the first surface filter layer and the sealing layer each covering the free surface of the container bottom, a bottom/side sealing apron whose lateral portion lightly abuts the casing abutting the sealing layer towards the top, a second filter layer with drainage pipes on which the stockpile material is stored being provided above and radially within the bottom/side sealing apron; as well as a releasable roof for cylindrical stockpile material containers with centrally charged circular conveyor for the stockpile material.
