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 ...

A two-stage metal valorisation process from electric arc furnace dust (EAFD)
Metalurgija, 2016 This paper demonstrates possibility of separate zinc and lead recovery from coal composite pellets, composed of EAFD with other synergetic iron-bearing wastes and by-products (mill scale, pyrite-cinder, magnetite concentrate), through a two-stage process. The results show that in the first, low temp erature stage performed in electro-resistant furnace,

Investigation of possibilities of EAFD pretreatment by pelletization and heat treatment for zinc valorization [PDF]
, 2013 The importance of EAF dust preparation is essential, both for environmental and technological reasons. EAF dust represents very harmful waste due to very fine particles consisting of various metals and metal oxides. In this paper the process of EAF dust pretreatment is shown, which consists of raw pellets formation and their annealing.
