Velike količine prašine iz EAF peći se stvaraju u Evropi (1,3 Mt), kao i u svetu (8,764 Mt). Zbog visokog sadržaja Fe i Zn, čiji sadržaj često dostiže ukupno između 50 i 60 tež. %, EAF prašina ima uvek bio interesantan za reciklažu. Do sada je najčešće primenjivana metoda obrade EAF prašine pirometalurški proces ekstrakcije Zn u Vaelz peći (85 % tržišnog učešća). U radu su predstavljene EIT sirovine Projekat: RIS-DustRec, koji ima za cilj razvoj inovativnih tehnologija za odvajanje, ponovnu obradu i upotreba svih komponenti EAF i CF prašine iz peći, kako bi se smanjila količina toksičnog otpada i postigao nulti otpad cilj u EU. Preliminarne hemijske, KSRD i SEM analize na dva uzorka prašine EAF i CF peći iz
Italija je izvedena i predstavljena.

Large amounts of EAF furnace dust are generated in Europe (1.3 Mt), as well as in the world (8,764 Mt). Due to the high content of Fe and Zn, whose content often reaches a total of between 50 and 60 wt.%, EAF dust has always been interesting for recycling. So far, the most commonly applied method of processing EAF dust is the pyrometallurgical Waelz kiln process of Zn extraction (85% market share). The paper presents EIT Raw Materials Project: RIS-DustRec, which aims to develop innovative technologies for the separation, reprocessing, and beneficial use of all components of EAF and CF furnace dust, to reduce the amount of toxic waste and achieve the zero-waste target in the EU. Preliminary chemical, XRD, and SEM analyses on two samples of EAF and CF furnace dust from Italy were performed and presented.
