  • Process for the preparation by crushing of scrap comprising metal parts provided with a surface coating
    Patent number: 5110427
    Abstract: 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 Soderberg mass of a carbon-containing mass for the production of cathode or anode blocks for the generation of aluminum by the Hall-Heroult process.
