The method is used to obtain metals, noble metals, and rare earth metals from scrap. The aim of the invention is to provide a method that allows an efficient recovery even from electronic scrap. This is achieved in that the scrap and carbon-containing materials (A) are oxidized with oxygen containing gases ( 11 ) in the presence of alkaline materials under overall reducing conditions with an overall lambda of <1 in an updraft gasifier ( 2 ) with a bulk material moving bed, said gasifier having a reduction zone ( 13 ) and an oxidation zone ( 7 ). The resulting syngas is drawn at the upper part ( 16 ) of the updraft gasifier, and the metals, noble metals, and rare earth metals are bound at least partly to the alkaline materials as oxides and/or in elementary form. Finally, said metals are obtained from the process as an enriched mixture (B) by means of physical separation methods. |
