“…Solidification/stabilization of EAFD has been investigated by several researchers (Andres and Irabien, 1994;Pereira et al, 2001;Flores-Velez and Dominguez, 2002;Fernandez et al, 2003;Fuessle and Taylor, 2004). Pereira et al (2001) stabilized EAFD using coal fly ash as the main binder, and reported that the final pH of the leachate must be within a range of values corresponding to the minimum solubility of the metals in the leaching medium, which is achieved in the pH 8.0-11.3 interval for TCLP leachates.…”

“…Stabilized wastes are considered acceptable for land disposal from the moment they pass TCLP standards. However, the treatment effectiveness may change later because of environmental conditions and slow physiochemical reactions during aging (Fuessle and Tylor 2004).…”

Abstract:In this study, solidifi cation/stabilization (S/S) of electric arc furnace dust (EAFD) which is generated during the production of steel from scrap metals and classifi ed as hazardous waste were investigated by using different ratios of cement and low grade MgO (LG MgO) as binding agents. Type I PC 42.5 R portland cement and LG MgO which contains 70-80% MgO were used. S/S blocks that contain different ratios of binding agents which have 1/0.5 -1/1 -1/2 -1/3 -1/4 -1/5 cement/LG MgO ratio and S/S blocks which contain only cement and no LG MgO agents were prepared. These blocks, which contain 3 different waste ratios according to weight, 20%, 30% and 40% respectively, were produced and exposed to 28-day water purifi cation. At the end of the purifi cation process, S/S blocks were extracted using TCLP (Toxicity Characteristic Leaching Procedure) tests in order to determine the leaching behavior of Zn, Pb, and Cd in S/S blocks. By the end of this study, it was concluded that the recovery of EAFD is possible and applicable by immobilization. The fi ndings of the study concluded that environmental performances or structural properties of blocks contain 30% waste by weight are suitable. This method is a proper one for recovering and treatment of EAFD with mixture of cement and LG MgO.

This study examined the effect of waste particle size on stabilization performance of hazardous electric arc furnace dusts (EAFD) from steel foundries through the measurement of the temperature rise during hydration and heavy metals leaching. EAFD was characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray fluorescence (XRF), granulometry, and acid neutralization capacity (ANC) analysis. Portland cement was used to stabilize EAFD. Two types of paste samples, with EAFD content varying between 0% and 50% by weight, were prepared. The first type contained original EAFD, and the second contained ground EAFD with increased surface area. The increase in the temperatures of the mixes was monitored during the hydration reactions of the pastes. Ground EAFD yielded higher temperature rise rates than the original EAFD. Heavy metals leaching were determined by toxicity characteristics leaching procedure (TCLP). Pastes containing ground EAFD up to 50% yielded lower zinc and lead leaching than that of samples containing original EAFD. The results revealed that surface area of the EAFD may affect the stabilization performance and therefore care should be given to storage conditions at the foundries.
