Abstract

L'invention concerne notamment le traitement des scories en vue de la récupération, sous une forme métallique relativement concentrée, de l'aluminium qu'elles contiennent Les scories sont traitées par passage entre des rouleaux 32 et dans des broyeurs successifs, ainsi que sur des tamis 14, 40. Les rouleaux 32 exercent seulement une compression limitée déterminée sur les scories, sans les broyer, pour rompre les liaisons entre les constituants métalliques et non métalliques. L'invention permet d'obtenir un produit de récupération à concentration métallique plus élevée que par les procédés antérieurs
