Abstract
The invention relates to a method for the processing of metal scrap, in particular steel scrap, wherein the metal scrap material is treated with at least one fluid with a view to removing surface coatings before a spectroscopic analysis of the metal scrap composition is performed. On the basis of this composition the metal scrap can then be sorted and further processed in a purposeful manner. Moreover, the fluid used for the removal of the surface coatings can be suitably treated to recover the metal constituents contained therein. On the one hand, a resource-conserving and economic recovery of metals, in particular zinc, contained in surface coatings is achieved by means of the inventive method and, what is more, the method also enables a purposeful sorting of metal scrap material to be performed for a variety of uses in the iron and steel producing industry.
