Reduction of electric arc furnace dust with solid iron powder
Canadian Metallurgical Quarterly, 1996Abstract Electric arc furnace (EAF) dust contains, on average, about 19mass% zinc and 3mass% lead. Due to the presence of this lead, as well as small amounts of cadmium and hexavalent chromium, EAF dust has been classified as a hazardous waste by various government regulatory agencies.

Mineral phases of weathered and recent electric arc furnace dust
Journal of Hazardous Materials, 2008A weathered and a recent sample of electric arc furnace dust (EAFD), generated in a southern Brazilian steel industry, were characterized by X-ray fluorescence spectroscopy (XFA), powder X-ray diffraction (XRD), thermogravimetric analysis (TG), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) probe and Fourier transform ...

Leaching properties of electric arc furnace dust prior/following alkaline extraction
Journal of Environmental Science and Health, Part A, 2007This study was carried out to determine the appropriate treatment of electric arc furnace (EAF) dust prior to permanent disposal. The total heavy metal content as well as heavy metal leaching from EAF dust was investigated in five composite samples obtained from three Croatian and Slovenian steelworks.

Electric Arc Furnace Dust Treatment Process by Iron Powder
Key Engineering Materials, 2015Electric arc furnace dust is a byproduct from steelmaking, contained up to 50%wt of zinc ferrite. It also contains about 10-20%wt of zinc oxide and the other metal oxides. Approximately 100,000 tons of EAF dust are generated per annum within Thailand. All of the dust has been sent to landfill.

Analytical Electron Microscopy Characterization of Electric Arc Furnace Dust
Proceedings, annual meeting, Electron Microscopy Society of America, 1981Alloy scrap metal is increasingly being used in electric arc furnace (EAF) steelmaking and the alloying elements are also found in the resulting dust. A comprehensive characterization program of EAF dust has been undertaken in collaboration with the steel industry and AISI.

A Sustainable Methodology for Recycling Electric Arc Furnace Dust
2018In a race to save the planet of its rapidly depleting natural resources, the use of Secondary Raw Materials (SRMs) as replacements in several processes is currently intensively pursued. In fact, this is currently one of the European Union (EU)’s mandates.

Processing of electric arc furnace dust via chloride hydrometallurgy
1994Production of steel in the electric arc furnace (EAF) generates a dust byproduct containing non-ferrous metals. In particular, zinc, lead and cadmium are volatilized at steelmaking temperatures and report as oxides or ferrites in the dust collected from EAF off-gas.
