Leaching and Geochemical Modelling of an Electric Arc Furnace (EAF) and Ladle Slag Heap

Abstract: Old metallurgical dumps across Europe represent a loss of valuable land and a potential threat to the environment, especially to groundwater (GW). The Javornik electric arc furnace (EAF) and ladle slag heap, situated in Slovenia, was investigated in this study. The environmental impact of the slag heap was evaluated by combining leaching characterization tests of landfill samples and geochemical modelling. It was shown that throughout the landfill the same minerals and sorptive phases control the leaching of e… Show more

“…Therefore, efforts should be made to characterize the leachability of contaminants using a variety of comprehensive methods, as has been advocated since the 1990s (Hage and Mulder, 2004). Previous studies (Bożym et al, 2021;Mizerna, 2015, 2016;Mizerna et al, 2017;Mizerna and Król, 2018) and scienti c reports on various materials, both construction materials and waste materials, show a variety of trends in the release of individual heavy metals depending on changes in a given factor using a given test method (Engelsen et al, 2017;Loncnar et al, 2022;Sun et al, 2019;van der Sloot et al, 2018). Consequently, there are di culties in unambiguous assessment of the leaching behaviour of heavy metals.…”

“…The multipurpose use rate of steel slag in China is less than 30%, of which less than 10% is used in building materials. Most steel slag is regarded as industrial waste, so it is filled or accumulated, resulting in ecological environmental pollution and other problems [ 1 , 2 , 3 , 4 , 5 ]. At the same time, China’s roads are in a stage of rapid development.…”
