Ironmaking, Vanadium Recovery, and Hydrogen Reduction Processes
This community focuses on the metallurgical processing of iron ores and the extraction of vanadium from industrial byproducts, with a significant emphasis on developing hydrogen-based reduction technologies to lower carbon emissions in steel production.
The work centers on the physicochemical mechanisms of reducing iron oxides, often utilizing hydrogen or biomass-derived reductants, and the subsequent separation of valuable metals like vanadium and manganese from furnace slags and residues. Recurring methods include acid leaching, solvent extraction, and magnetic separation applied to materials such as vanadium titanomagnetite and manganese residues. The research addresses the kinetics of phase transformations during sintering and pelletization, as well as the recovery of iron from complex waste streams. These processes are designed to improve resource efficiency and reduce the environmental footprint of heavy industrial production, specifically targeting the decarbonization of the iron and steel supply chain through alternative reduction pathways and cleaner extraction techniques.
The largest share of the community's output is found in iron research, accounting for 1.9% of all iron studies, with 7,719 papers in this group. Vanadium research also represents a significant portion, contributing 2.6% of all vanadium studies with 2,771 papers, while manganese research accounts for 1.4% of its field with 2,010 papers.
The community comprises 18,170 papers, published primarily in ISIJ International, Tetsu-to-Hagane, and the Journal of Iron and Steel Research International.
Recent work continues to focus on low-carbon sintering of iron ores, the recovery of iron from vanadium extraction tailings, and the application of hydrogen-based reduction to vanadium-titanium magnetite, alongside reviews of processing technologies for vanadium shale resources.
