The Russian steel and
iron ore producer
Metalloinvest Holding (
Metalloinvest) has announced that its subsidiary Mikhailovsky
Mining and Processing plant (Mikhailovsky GOK) has won the Russian Government Award in Science and Technology for development and implementation of its high-tech large-scale
iron ore production project in
Russia and for the introduction of innovative technologies in the
iron ore full-scale production process including all stages from
mining to processing.
Accordingly, unique and highly efficient innovative projects, successfully implemented at Mikhailovsky GOK, include: technology of dry magnetic separation for lean ore that enabled an increase in
iron ore concentrate production by two million mt per year, unique ‘Granulomer' ore milling control system, technology for additional dressing through flotation for magnetite concentrate and production of high quality
iron ore concentrate.
Mikhailovsky GOK's flotation plant produced hematite concentrate from wastes of the skimping separation process, the first plant in
Russia to do so. New technology allows the plant to increase output without boosting ore extraction volumes, to cut costs and decrease environmental impact.
