The HBI direct reduction process
As voestalpine, we plan to gradually switch from the coal-based blast furnace route to a green power-based electric steel route starting in 2027. This is made possible by a fundamental technological innovation. In addition to scrap and liquid pig iron, HBI is used, which is produced in the so-called direct reduction process.

Sponge Iron | SpringerLink
Sponge iron means porous iron produced by direct reduction process.Direct reduction (DR) process is a solid-state reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or …
Iron Sponge
Iron Sponge is most frequently supplied with 15 pounds of iron oxide per bushel of product. Iron Sponge, which has been used for many years to treat other gas streams, is a very simple way to remove the corrosive, bad smelling H2S. It works to effectively remove the sulfide from the gas stream by forming stable iron sulfide, a solid.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in …
Enhanced refractory organics removal by sponge iron …
Sponge iron (SFe) is a zero-valent iron (Fe0) composite with a high-purity and porous structure. In this study, SFe was coupled with microorganisms that were gradually domesticated to form a Fe0/iron-oxidizing bacteria system (Fe0-FeOB system). The enhancement effect of the Fe0-FeOB system on refractory organics was verified, the …

These processes operate with different feedstocks. The BF-BOF pathway converts raw iron ore to pig iron and then to steel HM – while EAF converts both steel scrap and sponge iron to steel HM. DRI converts raw iron ore to sponge iron, a porous, permeable, and highly reactive product that requires treatment with EAF before selling to …
Sponge Iron | A-One Steel Group
Sponge iron is obtained by direct reduction (elimination of oxygen) of iron ore, without melting it in a blast furnace. Sponge iron is an intermediate iron product used as a substitute for steel scrap while producing steel through the electric induction furnace route, the entire production of sponge iron is consumed in-house for the manufacturing of MS …
Sponge Iron | SpringerLink
Processes that produce iron by reduction of iron ore in solid state are generally classified as direct reduction (DR) processes and the products also referred …
After more than a century, iron sponge still soaks up …
The iron sponge technique originated in Europe more than 100 years ago, and the earliest operators used a naturally occurring form of hydrated iron oxide known as bog iron or bog ore. As refinements were made in the process, it was found that more efficient sulfur removal could be attained by uniformly distributing the iron oxide hydrate …

Powder Production Technologies
The sponge iron process. The longest established of these processes is the sponge iron process, the leading example of a family of processes involving solid state reduction of an oxide.
Direct reduced iron process
The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!
Iron Sponge Process
The Iron Sponge Process, a technology used for removing hydrogen sulphide (H2S) from biogas, can potentially use various biodegradable wastes as the supporting material for the H2S adsorption media, providing improved flexibility and cost-effectiveness. In this study, ground garden waste, digested garden waste, and spent tobacco were evaluated as …
