NLMK Stoilensky Begins Hot Testing at New Additional Beneficiation Section

Stoilensky Mining and Beneficiation Plant, part of NLMK Group, a global steel company, a Metal-Expo regular exhibitor, has started hot testing at three new concentrate grinding lines. The commissioning of the new additional beneficiation section will enable Stoilensky to increase its concentrate output from 17.5 million tonnes to 20 million tonnes per year and its ore processing capacity from 37 million tonnes to 42 million tonnes by 2021.

The new section will be integrated into a single process chain with three sections of the Beneficiation Plant. Having passed the medium to fine crushing stages and the high-pressure grinding rolls, ore will be fed into the three vertical mills for further crushing and beneficiation, before being supplied to the Pelletizing Plant for the production of pellets or being shipped to NLMK Lipetsk.

Investment in the project totalled about RUB 6 billion. The overall cost of the integrated project to increase ore mining and beneficiation capacities at Stoilensky, which also includes upgrading the existing beneficiation plant sections, the transport infrastructure, the waste management system, and transport procurement, will amount to RUB 16 billion.

Commissioning of the additional beneficiation section is scheduled for June 2020.
