Electric Arc Furnace Dust as a Valuable Production Residue from the Steel Production Process

Iako je elektropećna prašina zbog prisutnosti teških metala svrstana u opasni otpad, može se iskoristiti u razne svrhe, što je prihvatljiviji način njezina zbrinjavanja nego što je odlaganje na za to predviđena odlagališta, čime metali prisutni u prašini ostaju neiskorišteni. U radu je dan pregled nastanka elektropećne prašine, njezinih fizikalno-kemijskih svojstava i moguće uporabe. Imajući u vidu fizikalno-kemijska svojstva prašine i visok sadržaj željeza, veoma je pogodno rješenje njezino vraćanje u matični proces za dobivanje čelika. Dodatno, prašina se može rabiti u industriji neželjeznih metala za dobivanje teških metala kao što je cink te u nekim drugim industrijama (npr. za proizvodnju cementa, keramike, boja, itd.).

This paper presents a review of electric arc furnace dust, its physicochemical properties and possible use. With regard to the physicochemical properties of electric arc furnace dust and its high iron content, a very convenient solution is its return to the primary process of steel production. Furthermore, electric arc furnace dust can be used in the non-ferrous metal industry to obtain heavy metals, such as zinc, as well as in some other industries (e.g., cement, ceramics, paint, etc.).
