PAULO Ingeniería Flue dust characterization steelmaking waste steelmaking sludge Flue dust is as waste that can be obtained in the steelmaking process employing a LD converter as well an electric arc furnace. Several useful elements such as Fe and Zn can be found in this type of waste. Finding the best technology for processing this kind of material pass by knowing detailed how these elements are formed and combined. This study aimed to investigate the physical and chemical characteristics of a flue dust steelmaking sample, after weathering. The investigation was carried out by using X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, chemical analysis, particle size analysis, pycnometry and surface area measurement (BET). The waste studied, showed the predominance of wustite, magnetite, hematite, franklinite, graphite, calcite and quartz. Chemical analysis has pointed to 49.33 % Fe, 9.17 % CaO, 1.94 % MgO, 1.06 % Al2O3 contents. The median diameter (d50) was 44.04 µm, density was 2,990.0 kg/m³ and surface area was calculated to be 15,010.0 m²/kg. In the XRD pattern was observed peak overlapping, which was minimize employing previously a double leaching with 16.8 % mass concentration of hydrochloric acid solution. 2022 artículo científico 1518-1634 https://www.redalyc.org/articulo.oa?id=481582894014 en http://www.redalyc.org/revista.oa?id=4815 HOLOS application/pdf Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte HOLOS (Brasil) Vol.8 |
