Metalloinvest to Utilise Previously Unused Oxidised Iron Quartzites in New Production Facility

Metalloinvest plans to construct a new plant at its Mikhailovsky GOK unit in the Kursk region to process over 7 million tonnes of previously unused oxidised iron quartzites annually. This initiative, supported by a newly developed enrichment technology, aims to produce premium-quality iron ore concentrate suitable for green steel production, with operations slated to commence in 2028.
New Processing Plant for Oxidised Quartzites

The company will establish a new production facility designed to process oxidised iron quartzites, a resource that has historically been left unused due to a lack of appropriate technological solutions. Metalloinvest, in collaboration with Russian scientists, has successfully developed and implemented a novel technology for the enrichment of this specific type of ore. This breakthrough enables the valorisation of a substantial reserve, with the Mikhailovsky deposit holding an estimated 2.6 billion tonnes of oxidised iron quartzites.
Production of Premium Iron Ore Concentrate

The concentrate derived from these oxidised quartzites will possess a high iron content, reaching up to 68%, and a low level of silicon dioxide. This premium-quality output is specifically targeted for the production of iron ore pellets. These pellets meet stringent market requirements and are integral to the process of green metallurgy, particularly for applications relying on the direct reduction of iron.
Contribution to Green Steel Production

The iron ore concentrate produced from oxidised quartzites is a key component for green steelmaking, which utilises direct reduction of iron to significantly lower greenhouse gas emissions within the steel industry. Metalloinvest, already a major producer of hot briquetted iron—a form of direct reduced iron used in low-carbon steel production—is expanding its capacity to support environmentally conscious steel manufacturing. The initial capacity of the new plant is set at over 7 million tonnes per year, with potential for expansion to 11 million tonnes annually.
Economic and Employment Impact

The development of this new processing capability is projected to reduce ore extraction costs at the Mikhailovsky GOK operation. Furthermore, the project is expected to generate substantial employment opportunities, creating approximately 900 new jobs in the Kursk region. The overall investment for this significant project is estimated to exceed $2 billion.
