1. Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust
Abstract The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many different treatment processes for this issue, there is the possibility of returning the EAFD back to the Electric Arc Furnace. T

2. Carbothermic reduction of Electric Arc Furnace Dust via thermogravimetry
Abstract Electric Arc Furnace Dust (EAFD) is a solid waste originated from electric steelmaking furnaces. Currently, according to some authors, there is an estimated generation of 15 to 25 kg of dust per ton of steel produced. The formation of the dust is related to the following steps of the process: furnace charge, metal volatilization, iron vaporization u

3. Modificação e caracterização do resíduo pó de aciaria elétrica (PAE) para aplicação em reações de redução de cromo (VI)
In this study, electric arc furnace dust (EAFD) was thermally modified at different temperatures under H2 flow or charcoal in order to obtain reduced iron phases (Fe3O4, FeO and Fe0). The formation of these phases was confirmed by powder X-ray diffraction. The tests performed for reducing Cr (VI) using resultant materials obtained after thermal treatment of

4. Stabilization of electric-arc furnace dust in concrete
Electric-arc furnace dust (EAFD) is a by-product of steel production and recycling. This fine-grained material contains high amounts of zinc and iron as well as significant amounts of potentially toxic elements such as lead, cadmium and chromium. Therefore, the treatment and stabilization of this industrial residue is necessary. Concrete is a well-known suit

5. Characterization study of electric arc furnace dust phases
Electric arc furnace dust (EAFD) is a solid waste generated in the collection of particulate material during steelmaking process in electric arc furnace. The aim of this work is to carry out a chemical and structural characterization of two EAFD samples with different Zn contents. Optical emission spectroscopy via inductively coupled plasma (ICP), X ray diff

6. Reciclagem da poeira de aciaria elétrica na sinterização de minério de ferro visando a eliminação de zinco. / Eletric arc furnace dust recycling in iron ore sintering process aiming zinc removal
Este trabalho tem por objetivo estudar o aproveitamento do pó de aciaria elétrica (PAE) na sinterização de minério de ferro visando a eliminação de zinco. Primeiramente, foi feita uma caracterização física e química do resíduo através de análises químicas, granulométricas, morfológicas e de difração de raios-X. O minério de ferro, princip
