Investigation of possibilities of EAFD pretreatment by pelletization and heat treatment for zinc valorization [PDF]

, 2013
The importance of EAF dust preparation is essential, both for environmental and technological reasons. EAF dust represents very harmful waste due to very fine particles consisting of various metals and metal oxides. In this paper the process of EAF dust pretreatment is shown, which consists of raw pellets formation and their annealing.

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 ...
