Recovery of zinc from electric arc furnace dust by alkaline pressure leaching using iron as a reductant
TL;DR: In this article, a process of primary normal pressure leaching and secondary alkyl acid leaching was proposed to recover zinc from electric arc furnace (EAF) dust, and the main phase of zinc in normal leaching residue was determined to be zinc ferrite.

Sustainable synthesis of multiple-metal-doped Fe2O3 nanoparticles with enhanced photocatalytic performance from Fe-bearing dust
TL;DR: In this article, fabric filter dust was used as the starting material for the preparation of metal-doped Fe2O3 nanoparticles for the photocatalytic degradation of methyl orange aqueous solution.
Journal ArticleDOI
Application of alkaline solid residue of electric arc furnace dust for neutralization/purification of electroplating wastewaters.
TL;DR: Development of an appropriate procedure for the neutralization/purification of electroplating wastewater with alkaline solid residue (ASR) by-product of the alkaline extraction of zinc and lead from electric arc furnace dust (EAFD).

One-stage ultrasonic-assisted calcium chloride leaching of lead from zinc leaching residue
TL;DR: In this paper , an ultrasonic-assisted one-stage leaching process was developed and compared with a two-stage process under conventional conditions, and the results showed that Pb leaching efficiency reached up to 83.8% under the optimized onestage ultrasonic leaching conditions (including 480 W of ultrasonic power, 100 min duration, 350 g/L of CaCl2, 5:1 of liquid-solid ratio, 35°C, and pH of 3).

Electric arc furnace flue dusts: characterization and leaching with sulphuric acid
M. Cruells,Antoni Roca,C Núnẽz +2 more
TL;DR: In this article, an electric arc furnace (EAF) flue dusts characterization and a systematic study of sulphuric acid leaching to obtain the reaction rates of dissolution were examined.
Journal ArticleDOI
Hydrometallurgical recovery of zinc and lead from electric arc furnace dust using mononitrilotriacetate anion and hexahydrated ferric chloride.
TL;DR: The results of the normalized leaching test AFNOR X31-210 conducted on the leaching residues, shows that all the samples meet acceptance thresholds for hazardous wastes landfill, however, the residues contain a considerable amount of zinc as ZnFe2O4.

The precipitation of hematite from ferric chloride media
P.A. Riveros,John E. Dutrizac +1 more
TL;DR: In this paper, the precipitation of hematite from ferric chloride media was systematically investigated in a series of autoclave experiments and it was shown that the filterability of the fine precipitated hematites is greatly improved by the presence of hemetite seed.

Investigation of potential uses of electric-arc furnace dust (EAFD) in concrete
TL;DR: In this article, the results of standard tests on fresh concrete indicate that EAFD can be used as an effective set retarder and other standard tests appear to indicate that it will enhance engineering properties of hardened concrete without any side-effects.
