<p>The method according to the invention consists recovery noble-metals by removing the layer containing catalytically active noble-metal from the surface of the substrate by means of selective powdering, and separating the fine powder enriched in noble-metals obtained this way by means of physical operation from the monolith substrate remained substantially in its original state or being less powdered during selective powdering than the component containing catalytically active noble-metal or separating the fine powder enriched in noble-metal obtained this way and/or the noble metal content remained in the waste catalyst after selective powdering, by means of chemical operation. The fraction enriched in noble-metals can be processed by any metallurgical or chemical processes known per se.</p> |
