Metalloinvest launches shipments of premium quality pellets from Mikhailovsky GOK

18 October 2019

Metalloinvest, a leading global iron ore and HBI producer and supplier, and one of the regional producers of high-quality steel, has launched the shipment of premium quality pellets from Mikhailovsky GOK.

Pellets with a basicity of 1.0 (Fe content of >63%, compressive strength of >240 kg/pellets) were produced from a mixture of concentrate from Mikhailovsky GOK and Lebedinsky GOK and supplied to ArcelorMittal and Nippon Steel.

Metalloinvest has been implementing a number of comprehensive measures at Mikhailovsky GOK designed to improve the quality of iron ore concentrate and pellets. The installation of Derrick Fine Screening Technology at the beneficiation plant and modernisation of the pellet plants at the pelletising unit is ongoing.

Nazim Efendiev, First Deputy CEO, Sales Director of Management Company Metalloinvest, said: Our goal is to take the quality of Mikhailovsky GOKs products to the next level. The initial supplies of premium quality pellets have demonstrated that there is demand for these new products from the worlds leading metallurgical companies.

Sergey Pigarev, Head Metallurgist at Mikhailovsky GOK, commented: The qualities of pellets, such as durability, ability to be transported without losing quality and smelting efficiency are important for our customers. The enterprise is ready to adjust the quality characteristics of the products in line with demands of individual customers.

The equipment at Mikhailovsky GOKs Pellet Plant #3 was modernised for the production of pellets with high basicity. In particular, a new high-performance limestone weighing system was installed with an advanced automated control system. The capacity of the limestone feed bins was increased. At the site for thickening, filtration and raw pelletising, works were completed to expand the service sites.

Industrial production was preceded by a series of pilot laboratory studies followed by pelletising in real conditions. Specialists from NPVP TOREX, part of Metalloinvest, took part in the laboratory and industrial tests.

Following the introduction of fine screening technology, further improvements to the quality characteristics of the concentrate produced at Mikhailovsky GOK will allow the enterprise to expand the production of pellets with high basicity. Sections of the beneficiation plant with fine screening technology produce concentrate with Fe content 67%, and a lowered silica content.

Reducing the level of silica in the concentrate allows to achieve the necessary basicity of pellets with fewer fluxing additives. Thus, the productivity of pellet plants is increased while maintaining the necessary strength of the pellets.

At another Metalloinvest enterprise Lebedinsky GOK pellets with increased basicity have been in production for the past three years.
