The invention describes a process which enables the separation of permanent magnets out of a crap mixture. In order to achieve this thermal treatment is realized which leads to a partly demagnetization. This enables the following separation in an alternating magnetic field. This process leads to a separate fraction of corresponding permanent magnets. A German as well as an international patent application are pending. An experimental plant is build up. A proof-of-concept is realized. On behalf of the Westphalian University of Applied Sciences PROvendis offers licenses to interested companies.
