Cementing efficiency of electric arc furnace dust in mortars [PDF]
Construction and Building Materials, 2017 Abstract The aim of this study is to evaluate the cementing efficiency (k-value) of an electric arc furnace dust (EAFD), used in as-received conditions, as a supplementary cementing material (SCM). The investigated variables are the amount of EAFD in the mix, water/binder ratio and curing age.

The microwave processing of electric arc furnace dust [PDF]
JOM, 2008 An 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

Mineralogical characteristics of electric arc furnace dusts [PDF]
JOM, 1991 Reflected light microscopy can contribute important information regarding the mineralogy, mineral abundance, internal textures, sizes and shapes of particles in electric arc furnace (EAF) dusts. Scanning electron microscopy-energy dispersive spectroscopy and electron microprobe analysis are useful to determine the chemical compositions of the specific ...

Thermodynamic analysis of the selective chlorination of electric arc furnace dust
Journal of Hazardous Materials, 2009The remelting of automobile scrap in an electric arc furnace (EAF) results in the production of a dust, which contains high concentrations of the oxides of zinc, iron, calcium and other metals. Typically, the lead and zinc are of commercial value, while the other metals are not worth recovering.

Understanding Environmental Leachability of Electric Arc Furnace Dust [PDF]
Journal of Environmental Engineering, 2000 Dust 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 ...

Vitrification of electric arc furnace dusts
Waste Management, 2002Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits.

Enhancement of Electric Arc Furnace Dust by Recycling to Electric Arc Furnace
Journal of Environmental Engineering, 2002Electric arc furnace (EAF) dust is a hazardous waste product of the steelmaking industry with a high concentration of heavy metals, especially Zn and Pb. Existing treatment processes are industrially viable only when the zinc content is sufficiently high. In this research we present an industrial-scale process to enhance EAF dust by recycling it to the

Hydrothermal treatment of electric arc furnace dust
Journal of Hazardous Materials, 2011In this study, ZnO crystals were fabricated from electric arc furnace dust (EAFD) after alkaline leaching, purification and hydrothermal treatment. The effects of temperature, duration, pH, and solid/liquid ratio on ZnO crystal morphology and size were investigated. Results show a high reaction temperature capable of accelerating the dissolution of ZnO
