This study is aimed at developing a technology for processing electric arc furnace dust (EAFD) into granulated cast iron and zinc-containing product. The object was the from EAF of PJSC Magnitogorsk Iron Steel Works (Magnitogorsk, Chelyabinsk region). It has been established that contains valuable components in form ZnFe2O4 ZnO. EAFD involves reduction Fe Zn charge their oxygen-containing forms...

In this study, ferrochromium slag (FS) and electric-arc furnace dust (EAFD) samples were examined for their hazardous hexavalent chromium content mainly by X-ray photoelectron spectroscopy (XPS) analysis. According to the experimental results, magnesium-silicate constitutes main framework of both FS EAFD samples. Highly crystalline contains 3.11%Cr2O3 as spinel phases while constituent is much ...

The recent recovery processes of electric arc furnace dust (EAFD) include stabilization within materials with potential uses in the construction sector. EAFD by alkaline activation different alumina-silicates, resulting low-cost and environmentally friendly materials. leaching standards European regulations allow evaluating waste products. This work aims to study introduction FA–clay geopolymer...

World’s energy sources like petrochemical oils, natural gas and coal cause global warming environmental pollution. Therefore, the traditional must be replaced by renewable resources. Biodiesel has been recognized as one of effective, green, sustainable fuels. This paper investigates production biodiesel from sunflower oil using electric arc furnace dust (EAFD) a heterogeneous solid catalyst. Fo...

The vitrification of zinc-hydrometallurgy wastes, electric arc furnace dust (EAFD), drainage mud, and granite mud was shown to immobilize the hazardous components in these wastes. Batch compositions were prepared by mixing the wastes with glass-cullet and sand to force the final glass composition into the glass forming region of the SiO2-Fe2O3-(CaO, MgO) system. The vitrification was carried ou...

The electric Arc Furnace Dust (EAFD) sample leaching using two different organic carboxylic anions has been previously studied, as a separate article. aim of the present research work (Part II) is study on kinetics EAFD, comparing efficiency sodium citrate with that sulfuric acid solutions. effect solid / liquid ratio, temperature and reagent concentration in solutions metallic dissolution was ...

Electric arc furnace dust (EAFD) which is accumulated in large amounts world-wide contains hematite (Fe2O3) and significant quantities of magnetite (Fe3O4). Waste polyvinyl chloride (PVC) also poses a great environmental threat aside to EAFD. Both these wastes have shown potential for their co-thermal treatment metal extraction, thus minimising footprint. Herein, an investigation on the thermal...

This article shows the preliminary results of a study carried out to determine technical feasibility encapsulating high percentage EAFD in cement-based mortars manufactured with fine fraction recycled concrete aggregates (RCA). Two families mortars, natural aggregate as reference and RCA, were studied. An incorporation rate by weight two parts mortar one part was tested. The mechanical strength...
