Ironmaking - Direct reduction and smelting reduction

Oral Presentation

The steel industry is actively seeking innovative technologies to significantly reduce carbon footprints, especially for low-grade iron ores (BF quality), which constitute the majority of available iron ore resources and are primarily processed through the blast furnace route. The Circored process, developed by Metso, utilizes fluid bed reactors for the direct reduction of iron ore fines...

208. Decarbonization of industrial high-temperature processes with an innovative Electric Gas Heating

Ironmaking - Direct reduction and smelting reduction

Oral Presentation

Transitioning industrial processes to electric power offers the potential to decrease CO2 emissions by utilizing renewable energy sources. Electric gas heating enables more compact and efficient setups compared to traditional combustion heating methods.
Expected huge market demand of high temperature gas electrical heating in different industrial sectors cannot be covered only by available...

298. Clean iron production by self-reducing agglomerates made in biochar and mill scale: a comparison in reduction efficiency as a function of biochar quality and properties

Dr Gianluca Dall'Osto (Politecnico di Milano - Dipartimento di Meccanica)

Ironmaking - Direct reduction and smelting reduction

Oral

Carbon Composite Agglomerates (CCA) or self-reducing agglomerates are based on the compaction of a solid carbonaceous and oxide matrix in the form of pellets, briquettes, etc. with the possible addition of an organic or inorganic binder. As a result, when heated, the carbon acts as a reducing agent and the specific metals contained in the oxide matrix are recovered.
It is therefore not...

284. Enhancing Steelmaking Waste Utilization through Electric Smelting Furnace Technology

Kamal Joubarani (Hatch Ltd.)

07/10/2025, 11:50

Ironmaking - Direct reduction and smelting reduction

Oral Presentation

Steelmaking plants generate various waste materials, primarily slag, iron-containing fines, and sludges. Traditionally, many of the iron-bearing wastes have been recycled in integrated steel plants such as in sinter plants and blast furnaces. However, the shift to Electric Arc Furnaces (EAF) and stricter environmental regulations are diminishing the role of traditional recycling methods. As...

419. Comparative Analysis of CO and H2 Reduction Mechanisms in Electric Arc Furnace Dust

Eleonora Shpilevaia

Ironmaking - Direct reduction and smelting reduction

Oral

Recovering valuable metals such as zinc and iron from steel mill residues is crucial in the steelmaking industry. Electric arc furnace dust (EAFD) represents the primary secondary resource for Zn recovery, as electric arc furnace (EAF) technology predominantly utilizes galvanized steel scrap as its main feedstock. Waelz process, which has been recognized as the best available technology...

422. Electric Smelting Furnace Technology for Green Steelmaking

Kyle Chomyn (Hatch Ltd)

07/10/2025, 12:30

Ironmaking - Direct reduction and smelting reduction

Oral Presentation

The steelmaking industry is beginning to transition from carbon-intensive blast furnace production to new, lower-emission process routes. Implementation-ready solutions are needed to support this transition, but it is crucial that the industry makes careful investments to avoid risks to production.

The use of a direct reduction plant (DRP) with a downstream electric smelting (melting)...
