Abstract
La presente invenzione ha per oggetto un procedimento di riduzione degli ossidi di ferro e dei minerali di ferro contenenti ossidi. La riduzione del contenuto di ossigeno degli ossidi e dei minerali viene eseguita mediante macinazione in mulini ad alta energia degli ossidi o dei minerali con carbonio. Il procedimento può avvenire a temperatura ambiente. L'invenzione può trovare applicazione nel trattamento dei minerali di ferro contenenti ossidi di ferro, nel diminuirne la quantità di ossigeno presente a livelli inferiori e quello della wustite (FeO). Il minerale così parzialmente preridotto può servire come materiale di carica all'altoforno per la fabbricazione di ghisa, al convertitore o al forno elettrico per la fabbricazione di acciaio.
