Abstract

Procedimento di recupero di materie prime e residui utilizzabili a partire da scorie di acciai speciali per produrre scorie utilizzabili come concime in agricoltura di dimensioni comprese tra 0 e 4 mm, scorie di dimensioni maggiori di 4 mm e particelle metalliche utilizzabili come materia prima. Il procedimento realizza una separazione densimetrica della scoria iniziale mediante una disgregazione selettiva della stessa per mezzo di vagli, mulini e tavole pneumatiche disposte adeguatamente.
