PROCESS FOR THE PREPARATION BY CRUSHING OF SCRAP COMPRISING METAL PARTS PROVIDED WITH A SURFACE COATING

摘要

Known processes for the preparation by crushing of scrap comprising metal parts provided with a surface coating have the disadvantage that they are very complex and/or only allow the reuse of one component of the scrap. These disadvantages can be avoided if the crushed parts are fed to a carbon-containing mass used in the electrochemical industry, in particular a S?derberg mass or a carbon-containing mass for the production of cathode or anode blocks for the generation of aluminium by the Hall-Heroult process.
