ALTERNATIVE NON-HYDROMETALLURGICAL ROUTES FOR ELECTRIC ARC FURNACE DUST (EAFD) TREATMENT: A CRITICAL REVIEW [PDF]
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 [PDF]
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 ...

Effect of water and alkali content on setting time of cement pastes with electric arc furnace dust (EAFD) [PDF]
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 ...

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.
