Investigation of composition and properties of EAF dust for metal reduction

In this work, we investigated the composition and structure of the dust of electric arc steelmaking furnaces. We considered the process of direct reduction of metals (mainly Zn and Fe) with biochar from EAF dust. For better control over chemical transformations, it is proposed to use microwave heati...

Zusammenfassung:In this work, we investigated the composition and structure of the dust of electric arc steelmaking furnaces. We considered the process of direct reduction of metals (mainly Zn and Fe) with biochar from EAF dust. For better control over chemical transformations, it is proposed to use microwave heating of a mixture of EAF dust and biochar. Possible chemical and phase transformations for complex oxides in the composition of EAF dust have been determined.
