Method for extracting the anode butt (110) and the thimbles (130) attached to a spent anode or a scrapped fresh anode, comprising the following steps: (a) placing the butt (110) between a stop device (200) and an attacking device (300), said stop device having a first stop (211) blocking the butt, said attacking device being provided, around each rod, with a recess having a second stop that blocks said thimbles, the axial distance between the stops being equal to or greater than the height of the thimbles; b) displacement of the butt so that it comes up against the first stop; c) displacement of the attacking device; the butt fragments; d) removal of the butt fragments; e) continuation of the attacking device displacement; the thimbles are detached from the rods; f) the attacking device is stopped and withdrawn. In two well-separated successive steps, the butt fragments and the thimbles become detached, drop off and can be sent directly to a specific recycling shop. |
