Pyrometallurgical recycling of electric arc furnace dust
Journal of Cleaner Production, 2017Electric arc furnace (EAF) dust is an important secondary resource which contains multiple metallic elements, such as zinc, lead, iron, chromium and cadmium. Recycling of EAF dust is not only favorable to increasing economic potential of the dust by recovering these valuable metals, but also of benefit to solving disposal and environmental problems ...

Hydrometallurgically recovering zinc from electric arc furnace dusts
JOM, 2001The increasing use of zinc-containing scrap for steel production has lead to a high zinc content in the electric arc furnace and converter flue dusts. The cost of disposing of this residue is high due to environmental restrictions. Various recycling processes have been developed for these dusts, but most never reached the pilot plant stage and many ...

The microwave processing of electric arc furnace dust
JOM, 2008An ideal treatment for electric arc furnace (EAF) dust is to cost-effectively process the dust on site to generate high-value products. Microwave heating has the potential to be the ideal approach. In this study, testing was conducted to evaluate the feasibility of treating EAF dust under microwave radiation to produce iron metal and zinc metal instead

Characterization of Sintering Dust, Blast Furnace Dust and Carbon Steel Electric Arc Furnace Dust
2015In order to make a complete understanding of steel plant metallurgical dusts and to realize the goal of zero-waste, a study of their properties was undertaken. For these purposes, samples of two sintering dusts (SD), two blast furnace dusts (BFD), and one electric arc furnace dust (EAFD) taken from the regular production process were subjected to a ...

Understanding Environmental Leachability of Electric Arc Furnace Dust
Journal of Environmental Engineering, 2000Dust from production of steel in an electric arc furnace (EAF) contains a mixture of elements that pose a challenge for both recovery and disposal. This paper relates the leachability of six Canadian EAF dusts in four leaching tests [distilled water, Ontario Regulation 347 Leachate Extraction Procedure, Amount Available for Leaching (AALT), and pH 5 ...

The flash reduction of electric arc furnace dusts
JOM, 1992The flash processing of electric arc furnace (EAF) dusts is a promising method for recovering zinc and producing nontoxic slags for direct disposal. In order to reduce the zinc content of the dust particles and maintain the iron content in oxide form, a certain range of temperature and oxygen potential must be provided, as dictated by thermodynamic ...

Characterization of directly sampled electric arc furnace dust
AIP Conference Proceedings, 1982As one part of a project to characterize electric arc furnace dust, direct sampling of particulates inside two furnaces has been undertaken. The sampled particles from two separate furnace runs were characterized by analytical electron microscopy. The elemental analyses were performed using energy dispersive x-ray analysis.

Characterization of Low-Zinc Electric Arc Furnace Dust
2017Electric arc furnace (EAF) dust is an important secondary resource that should be recycled to enhance its considerable economic value and potential environmental benefit. In this study, a low-zinc EAF dust was characterized by various techniques, including chemical titration, X-ray diffraction, granulometric analysis, scanning electron microscopy and ...

Study on Recycling of Electric Arc Furnace Dust
Materials Science Forum, 2014Electric arc furnace steelmakers are finding that dealing with the dust is increasingly difficult. Stockpiling this dust on site, recycling or sending offsite for disposal all entail considerable difficulties and costs. Succesful recycle of the valuable metals (iron, zinc) present in electric arc furnace dust will result in resource conservation while ...

Microwave caustic leaching of electric arc furnace dust
Minerals Engineering, 2000Abstract Electric arc furnace (EAF) dust is a waste product which is generated when steel scrap is melted in an electric arc furnace. It contains high concentrations of iron, zinc and lead. Numerous pyrometallurgical and hydrometallurgical processes have been developed to treat this material.
