VERFAHREN UND ANLAGE ZUR RÜCKGEWINNUNG VON ALUMINIUM AUS ABFÄLLEN UND RESTSTOFFEN

摘要

Recovering aluminium from waste materials covered with organic compounds comprises: (i) carbonising the organic compounds by pyrolysis, with formation of pyrolysis gases and coke; (ii) removing the pyrolysis coke from the pre-treated material and non oxidising annealing; and (iii) melting the remaining material. Also claimed are an installation for implementing the above method, and an application of the separated pyrolysis coke for manufacture of carbon electrodes used in aluminium production.
