EAF dust: An overview on the influences of physical, chemical and mineral features in its recycling and waste incorporation routes

Journal of Materials Research and Technology, 2017
Electric-arc furnace dust (EAFD) is one of the several process residues generated in mini mills during steel production. The presence of valuable zinc in EAF dust and the rising costs for waste disposal are the motivating factors for EAFD recycling or ...

Influence of electric arc furnace dust and lime kiln waste in Portland cement hydration [PDF]

, 2020
Studies have indicated that the use of electric arc furnace dust (EAFD) results in a delay in the hydration time of Portland cement. Calcium-rich waste such as lime kiln waste (LKW) is one of the techniques used to offset this delay as it accounts for ...

Hybrid Hydro-pyrometallurgical Process for Zn Recovery from Electric Arc Furnace Dust [PDF]

, 2022
Electric arc furnace dust (EAFD) which is considered hazardous waste, contains significant amounts of Zinc (Zn), iron (Fe), and some dangerous elements. Zn exists in the dust as Zinc Oxide (ZnO) and Zinc Ferrite (ZnFe2O3) which is difficult to be leached

Promotion of Circular Economy: Steelwork Dusts as Secondary Raw Material in Conventional Mortars

Proceedings, 2018
Among the actions proposed by the European Union for the implementation of Circular Economy is the use of waste as a secondary raw material (SRM). During the fusion of the scrap, a steel dust is generated, named Electric Arc Furnace Dust (EAFD). The EAFD
