Abstract: Method of de-coating metallic coated scrap pieces, the metallic coated scrap pieces comprising a metallic core layer and a metallic coating layer of which the liquidus temperature of the metallic coating layer is lower than the solidus temperature of the metallic core layer, such as brazing sheet scrap pieces, or from metallic coated scrap pieces of which the upper part of the melting range of the metallic core layer has an overlap with the lower part of the melting range of the metallic core layer. The metallic coating layer is at least partially removed from the metallic core layer of said scrap pieces by agitating the scrap pieces at an elevated temperature T above the solidus temperature of the metallic coating layer and below the liquidus temperature of the metallic core layer, together with abrading particles. The abrading particles are brought into fluidisation during the agitating of the metallic coated scrap pieces, thereby forming a fluidised bed.
