Revista Multidisciplinar do Nordeste MineiroElectric arc furnace dust (EAFD) is a hazardous by-product from steel production in electric arc furnaces, characterized by a complex chemical composition and high concentrations of heavy metals such as zinc, lead, and iron. This review aims to critically evaluate the main non-hydrometallurgical treatment routes applied to EAFD, focusing on ...

Process Route for Electric Arc Furnace Dust (EAFD) Rinse Wastewater Desalination
ProcessesThis study introduces a two-step treatment method for synthetic and real electric arc furnace dust (EAFD) wastewater, integrating sorption with Mg–Al layered double hydroxides (LDHs) and electrodialysis (ED). The hydrotalcite (LDH), mainly Mg6Al2(CO3)OH16·4H2O (hydrotalcite-2H), was characterized by XRD, FTIR, SEM, and EDX, confirming its layered ...

Thermodynamic and kinetic investigation of carbothermic reduction of electric arc furnace dust [PDF]
Metalurgija, 2022 The thermodynamics and kinetics of electric arc furnace dust (EAFD) reduction were studied experimentally. The oxygen potential in the systems was determined by the electromotive force (EMF) method. Experimental equations for ΔG = f(T) were derived.

Sustainable Construction Materials and Technologies (SCMT), 2019 This study was undertaken to provide additional information about the effects of varying water-binder ratio (0.30-0.55) and electric arc furnace dust (EAFD) content (up to 20%) on setting times of blended cements. A study about the influence of total alkali content on setting time of blended cement was also conducted as an attempt to identify an ...

Investigation of selective leaching conditions of ZnO, ZnFe2O4 and Fe2O3 in electric arc furnace dust in HNO3 [PDF]
Journal of the Serbian Chemical Society, 2022 Electric arc furnace dust (EAFD) includes mainly Zn, Fe, Pb, Ca and Mn-bearing compounds. Thus, EAFD is classified as a hazardous waste. The dissolution behavior of Zn- and Fe-bearing compounds in EAFD in nitric acid solutions was investigated in this ...

Microwave selective heating of electric arc furnace dust constituents toward sustainable recycling: Contribution of electric and magnetic fields [PDF]
, 2021 Microwave heating of waste electric arc furnace dust (EAFD) for the purpose of its remediation has been studied extensively. However, these studies considered EAFD as a bulk material without addressing either the relative response of its individual ...

Case Studies in Chemical and Environmental Engineering, 2023 Efficient decontamination of 137Cs in electric arc furnace dust (EAFD) was carried out using a solid-liquid extraction method and then the obtained wastewater contaminated with 137Cs was treated by a co-precipitation. The influences of pH, stirring time,

steel research international, Volume 91, Issue 11, November 2020., 2020 A novel process for extraction, storage, and utilization of off‐gas waste heat is discussed. Key difference to other concepts is the application of entrained flow Ca(OH)2 dehydration. Waste heat exchangers are avoided. Balancing of power‐off times for the reference plant requires just small heat storage tanks of 6.5 m3. In total, a net power generation
