EAF dust: An overview on the influences of physical, chemical and mineral features in its recycling and waste incorporation routes

Journal of Materials Research and Technology, 2017
Electric-arc furnace dust (EAFD) is one of the several process residues generated in mini mills during steel production. The presence of valuable zinc in EAF dust and the rising costs for waste disposal are the motivating factors for EAFD recycling or ...

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 ...

Laboratory Investigation to Evaluate the Effect of Electric Arc Furnace Dust (EAFD) on Properties of Asphalt Concrete

Environment and Natural Resources Research, 2013
أحد المنتجات الثانوية الخطرة لصناعة الصلب هو غبار فرن القوس الكهربائي EAFD. تم تقدير أنه لكل طن من الفولاذ المنتج هناك حوالي 15-20 كجم من EAFD. بسبب احتوائه على معادن ثقيلة مثل الزنك أو الكوبالت أو النحاس أو الرصاص أو الكادميوم، تم تصنيف هذا الغبار على أنه خطير، وبالتالي يجب معالجته بشكل مناسب لحماية environment.Solidification/stabilization تم استخدامه
