Abstract

L'invention concerne des procédés et des appareils pour traiter des scories d'aluminium, des scories de zinc ou des résidus riches en métaux. Ces procédés consistent : à chauffer des scories d'aluminium, des scories de zinc ou des résidus riches en métaux dans un four à induction pour induire un courant électrique dans au moins un métal contenu dans les scories d'aluminium, des scories de zinc ou des résidus riches en métaux, et chauffer le ou les métaux à une température supérieure au point de fusion de ces métaux pour provoquer la fusion et l'agglomération du ou des métaux au niveau d'une partie inférieure du four ; et à éliminer le ou les métaux en fusion du four de façon à séparer le ou les métaux en fusion des scories d'aluminium, des scories de zinc ou des résidus riches en métaux.
