    Feb 15, 2014 1. Introduction. During the melting of steel scrap in an electric arc furnace (EAF), around 11–20 kg of dust (EAFD) is formed for each ton of produced steel (Liebman, 2000).This dust, which is rich in Fe and Zn oxides, was classified as a hazardous waste in the late 1980s by the Environmental Protection Agency (EPA), because it contains leachable Cd, Pb, and Cr(VI) (Assis, 1998)

    Mar 10, 2021 Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (∼1600 C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the
