SOLVENT EXTRACTION OF ZINC FROM ACIDIC LEACH SOLUTIONS [PDF]
Sustainable Extraction and Processing of Raw Materials Journal, 2021 . An initial test work was carried out to demonstrate that solution produced by autoclave acid leaching of Electric Arc Furnace Dust (EAFD) from the steel production could be processed through solvent extraction (SX) to recover zinc.

Recovery of Cs-137 from electric arc furnace dust by lixiviation
, 2022 An orphan radioactive source of Cs-137 was inadvertently melted in an electric arc furnace, generating large volumes of electric arc furnace dusts contaminated with Cs-137 (137Cs-EAFD). This work proposes the Cs-137 recovery from 137Cs-EAFD by applying a

Determination of ZnO Amount in Electric Arc Furnace Dust and Temperature Dependence of Leaching in Ammonium Carbonate by Using of X-Ray Diffraction [PDF]
Archives of Metallurgy and Materials, 2018 Zinc is present in electric arc furnace dust (EAFD) mainly in two basic minerals, namely as franklinite ZnFe2O4 and/or zincite ZnO. While zincite is relatively reactive and easily treatable, franklinite is considerably refractory, which causes problems ...

The pyrometallurgical recovery of zinc from electric arc furnace dust (EAFD) with active carbon
IOP Conference Series: Materials Science and Engineering, 2019 Abstract The reduction of minor impurities (e.g., Ferrite, Magnesium, Lead, Chromium) from Zinc rich-EAFD with active carbon addition was investigated at temperature between 900-1300 °C. The result was powder with higher zinc content which then analysed by X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD) and scanning ...

Engineering Reports, Volume 7, Issue 3, March 2025.The utilization of waste‐based, thermal energy‐storing building materials in construction may help reduce the environmental impact of human activities. However, most studies on phase change materials (PCM) tend to concentrate on the basic properties of these materials, and thus fail to provide a comprehensive perspective on sustainability.
