| Özet |
| An EAF dust sample generated in a scrap based steel mill was treated by a combination of hydro-and pyrometallurgical techniques. The EAF dust contained mainly ferritic spinels forming solid solution phases according to the general chemical formula (MnxZnyFe1-xy) Fe2O4 and other oxide phases such as ZnO, CaO and Ca2Fe2O5. The EAF dust was first treated by hydrochloric acid leaching at pH= 3 which dissolved 63% of the zinc. The pyrometallurgical treatment of the leaching residue was studied using an induction heating system to simulate some important operations of EAF smelting of the residue in combination with steelmaking. The leaching residue was mixed with carbon powder to obtain a mixture with 52.1% ZnFe2O4 and 17.8% carbon. The mixture, scrap, and slag former were charged together in a crucible and heated to attain a melt temperature around 1650DGC. The effects of different amounts of mixture on the zinc balance and iron recovery were examined. Based on the test results, suggestions are made for the EAF recycling procedure of the leaching residue. |
