摘要： Disclosed is a method for sorting of scrap metal in which a composition analysis is carried out on a scrap fragment. Surface composition information about the local composition of the scrap fragment is determined, and associated volumetric composition information about the composition of the scrap fragment is assigned to the scrap fragment depending on the surface composition information determined by measurement and on a given assignment rule. Also disclosed is an apparatus for sorting scrap metal having a conveyor designed to convey a quantity of scrap fragments, an analysis device designed to carry out composition analyses on scrap fragments, and a control device designed to assign associated volumetric composition information about the composition of the scrap fragment. A composition analysis of a scrap fragment includes determining surface composition information about the local composition of the scrap fragment by measurement.
