The invention relates to a process and an apparatus for the treatment of secondary raw materials, especially for the treatment of electronic scrap. The problem here is that the individual fractions of useful materials are to be obtained as highly sorted as possible. For this purpose, according to the process provided, after preliminary dismantling and/or in the equipment of a comminuting and classifying arrangement, sorting by means of sensors and discharge devices is initiated.
