“…Fine scale (below 2 mm) from the secondary settling tanks of a rolling mill contains about 10 mass% of water and 15 mass% of oil. Degreasing and dewatering are complicated technological tasks hindering utilization of scale [24]. In our case the bound water, at least partly, could be split to hydrogen.…”

Development of reliable and cost-effective technologies to produce hydrogen is very important in the context of climate change mitigation. Even partial substitution of carbonaceous fuels and reductants in ironmaking may reduce CO 2 emissions considerably. Hydrogen-based ironmaking technologies are being developed; however, their commercialization is constrained by availability and cost of hydrogen. Approaches such as solar hydrogen, fuel cells, and bio-hydrogen are being extensively studied worldwide; however, for the most part, these developments have uncertain potential to produce hydrogen for industrial applications in ironmaking owing to their complexity, insufficient productivity, and high cost. The potential of some widely available materials and wastes to be used as contact mass in the thermo-chemical water splitting processes for on-site production of hydrogen at a steel factory towards future hydrogen-based ironmaking is studied in the current paper by using thermodynamic modeling.

“…Carbon reduces the leaching residue into iron and zinc at high temperatures, so the combination of these two methods can be applied [6]. Mill scale is generated in steelmaking industry; it mainly consists of iron oxides and relatively small amounts of the sulfur, phosphorus, and alkalis [7]. The chemical energy provided by an optimized carbon/oxygen ratio can replace the part of electrical energy for recovery of iron and zinc in an EAF dust.…”

Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required for smelting. Modelling was performed with the software named RikiAlC. The crude ZnO, slag, and metal phase were analyzed using the atomic absorption spectrometry (AAS), the optical emission spectrometry with inductively coupled plasma (ICP-OES), the X-ray diffraction (XRD), the scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS), and reflected and transmitted light microscopy. Also, in order to follow the behavior of this process the exhausted gases were monitored. The synergetic effects of the designed mixture may be recognized in minimizing energy consumption for the smelting process, improving the product yield efficiency, and reducing the negative environmental effects.
