Iron Ore Preparation: Iron ore is first crushed and ground to a suitable size for processing. The ore is then either pelletized or formed into briquettes using binders.

Reduction: The prepared iron ore is fed into a furnace or reactor where it is subjected to a reducing atmosphere at high temperatures (typically between 700°C to 1100°C). The reducing gas, usually a mixture of hydrogen and carbon monoxide, reacts with the iron oxide in the ore, causing it to lose oxygen and form metallic iron.

Formation of Briquettes: The reduced iron is then formed into briquettes or pellets using a binder, typically a small amount of a binding agent such as bentonite or lignosulfonate. This step helps to improve the handling and transportability of the HBI.

Cooling and Handling: Once formed, the HBI briquettes are cooled and then handled for storage or transportation to steelmaking facilities.

Properties of HBI

Hot Briquetted Iron possesses several properties that make it an attractive feedstock for steelmaking:

High Iron Content: HBI typically contains around 90-94% metallic iron, making it a highly concentrated source of iron for steel production.

Low Impurity Content: The reduction process removes impurities such as silica, phosphorus, and sulfur, resulting in a cleaner iron product compared to traditional ironmaking methods.

High Density: HBI has a high density, which allows for efficient transportation and storage, reducing logistical costs.

Uniform Composition: Due to its manufacturing process, HBI has a uniform composition and size, which contributes to consistent steel quality during the steelmaking process.


Hot Briquetted Iron finds application primarily in the steelmaking industry as a feedstock for electric arc furnaces (EAFs) and basic oxygen furnaces (BOFs). Some common applications of HBI include:

EAF Steelmaking: HBI can be directly charged into electric arc furnaces, where it is melted along with scrap steel to produce high-quality steel products.

BOF Steelmaking: HBI can also be used as a supplement or alternative to traditional iron ore in basic oxygen furnaces, where it is melted and converted into liquid steel.

Reducing Agent: HBI can serve as a reducing agent in various metallurgical processes, such as the production of ferroalloys or in the production of iron powders.


Hot Briquetted Iron (HBI) is a valuable feedstock in the steelmaking industry, offering advantages such as high iron content, low impurity levels, and uniform composition. Its production process, which involves direct reduction of iron ore, results in a high-quality iron product suitable for various steelmaking processes. As the steel industry continues to evolve, HBI is expected to play an increasingly important role in meeting the demand for high-quality steel products while reducing environmental impact.
