Mikhailovsky GOK produces 3 million tonnes of concentrate using fine screening technology

Mikhailovsky GOK (part of Metalloinvest) has produced 3 million tonnes of fine screening technology concentrate. The advanced iron ore beneficiation technology using Derrick equipment was launched at the plant in September 2019.

Alexander Levshin, Chief Engineer at the beneficiation plant, said: "This is an important occasion not only for our division, but also for the entire plant. The beneficiated concentrate with an iron content of 67% is used to produce premium quality pellets. Achieving such production volumes confirms that our enterprise’s products are in demand among metals and mining customers."

The new technology is implemented at four sections of Mikhailovsky GOK’s beneficiation plant. The produced concentrate, with increased iron content and reduced silicon dioxide content, is a raw material used in the production of pellets at the pelletising unit with varying quality characteristics according to customer needs.

Currently, Metalloinvest is building a separate concentrate beneficiation facility as part of the second stage of the fine screening technology implementation project at Mikhailovsky GOK. In 2022, the entire beneficiation division of the plant is expected to switch to the production of high-quality concentrate with an iron content of 68.8%-70%.

Improving concentrate and pellet quality will strengthen the competitive advantages of Mikhailovsky GOK's products and open up new sales markets. In addition, refractory quarry ores will be involved in the processing, which will allow for the responsible and comprehensive use of the deposit's reserves.
