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.

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 ...

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 ...
