Primetals and Midrex

Estimated Cost:




Mikhailovsky HBI, which was jointly established by USM and Mikhailovsky GOK (part of Metalloinvest), signed a contract with Primetals Technologies and consortium partner Midrex Technologies, Inc. to supply a new Hot Briquetted Iron (HBI) Plant in Zheleznogorsk, Kursk region, Russia.


The plant is designed to produce 2.08 million metric tons of HBI per year. Latest design features ensure reduced energy consumption and environmental impact. The contract includes engineering, supplies and advisory services. Startup is expected in the first half of 2024.

The new contract once again proves Midrex-based direct reduction technology as the leading technology in the market with a market share of 80%.

The new plant will be the largest HBI plant in the world and is equipped with the latest design features. The plant includes a 7.15m diameter Midrex shaft furnace, a 19-bay reformer with 280mm MA-1 reformer tubes and low NOx burners for NOx reduction. An increased top gas pressure ensures higher furnace productivity and reduced power consumption. A flue gas hot fan additionally reduces electric power consumption. Also, a hot fines recycling system will be included. The level 1 and level 2 automation systems, including the DRIpax expert system, are also part of the project.

The Midrex plant produces high-quality HBI from iron ore pellets using the natural gas-based Midrex Direct Reduction Process (Midrex NG) - the most environmentally friendly technology for ore-based ironmaking.

Investment in the construction of the plant is estimated at over 40 bn roubles excluding VAT. The project will create around 400 highly qualified jobs in Zheleznogorsk.
