Taimyr Peninsula (Polar Division and Medvezhy Ruchey)
Polar Division and Medvezhy Ruchey are the Group’s flagship subsidiaries featuring a full metals production cycle that embraces operations ranging from ore mining to the shipment of end products to customers. Operating the Company’s largest fields, they mine ca. 17 mtpa of ore. In 2017, Polar Division and Medvezhy Ruchey accounted for 77% and 35% of copper and PGM output, respectively.
They are located beyond the Arctic Circle on the Taimyr Peninsula in the north of the Krasnoyarsk Territory, Russia. The sites are linked to other regions by the Yenisey River, the Northern Sea Route and by air.
The Talnakhskoye and Oktyabrskoye Fields are developed by Taimyrsky, Oktyabrsky, Komsomolsky (including Komsomolskaya and Skalistaya mines) and Mayak mines. Ores are extracted through slicing and chamber mining with flowable backfilling.
The Norilsk-1 Field is developed by Zapolyarny mine through open-pit and underground mining. Underground mining is carried out through level caving using single-stage excavation and front ore passes.

|Zapolyarny open pit||open pit||disseminated|
In 2017, Polar Division’s total ore output stood at 17.4 mt, up 133 kt, or 0.8% y-o-y. The production of high grade and cupriferous ores increased by 6.5% and 1.2% y-o-y, respectively, driven by the performance of Taimyrsky mine and Skalistaya mine demonstrating a 40% growth y-o-y. Cupriferous ore production was higher thanks to Oktyabrsky mine’s results. In 2017, disseminated ore production was down by 9% – primarily due to lower output at Zapolyarny mine. The change in the volumes of ore mined was in line with the annual production plan.
- Talnakh Concentrator
- Norilsk Concentrator (now part of Medvezhy Ruchey)
Talnakh Concentrator processes high grade and cupriferous ores from the Oktyabrskoye Field to produce nickel-pyrrhotite and copper concentrates and metal bearing products. The key processing stages include crushing, breaking, flotation and thickening.
Norilsk Concentrator processes cupriferous and all disseminated ores from the Talnakhskoye and Oktyabrskoye Fields and Copper Plant’s low grade ores to produce nickel and copper concentrates. The key processing stages include crushing, breaking, gravitation and flotation enrichment, and thickening.
Thickened concentrates are transported via a pipeline from Talnakh and Norilsk Concentrators to smelting facilities for further processing.
In 2017, Polar Division’s Production Association of Concentrators processed a total of 18 mt of feedstock (including high grade, cupriferous and disseminated ores).
In 1H 2017, Talnakh Concentrator operated against the backdrop of implementing and fine-tuning a new technology, moving on to reach the design capacity in 2H 2017 and beat the 2016 ores processing volume by 1.5 mt in the full year (10.0 mt vs 8.6 mt). Nickel recovered into collective flotation concentrate from ore processed increased by 2.2% y-o-y (81.7% vs 79.5%).
In 2017, volumes of ore processed at Norilsk Concentrator were 0.6 mt lower (7.5 mt vs 8.1 mt in 2016) – in line with the mining plan. Nickel recovered into collective concentrate was 0.8% higher (71.7% vs 70.9% in 2016). During the year, the facility processed significant volumes of Copper Plant’s low grade ores.
- Nadezhda Metallurgical Plant
- Copper Plant (CP)
- PGM Concentrator (part of Copper Plant)
Nadezhda Metallurgical Plant produces converter matte and elemental sulphur from the following:
- Talnakh Concentrator’s nickel-pyrrhotite concentrate and metal bearing products;
- Norilsk Concentrator’s nickel concentrate;
- pyrrhotite concentrate previously stored at Kayerkansky Open Pit Coal Mine (KUR-1).
Pyrrhotite concentrate from Talnakh Concentrator and stored pyrrhotite concentrate from Kayerkansky Open Pit Coal Mine is further leached in Hydrometallurgical Shop to produce steam cured sulphide concentrate. Concentrate from Talnakh Concentrator, steam cured sulphide concentrate and stored pyrrhotite concentrate from Kayerkansky Open Pit Coal Mine are delivered to the flash smelting furnaces. The matte is then blown into high grade converter matte.
Copper Plant processed all of the copper concentrate from Norilsk and Talnakh Concentrators, as well as third-party feedstock, to obtain copper cathodes, elemental sulphur and sulphuric acid for production needs of Polar Division.
PGM Concentrator (part of Copper Plant) recycles sludge from the tank-house to produce concentrates of precious metals and technical selenium.
Precious metals produced by Polar Division are refined at Krasnoyarsk Precious Metals Refinery under a tolling agreement.
At Polar Division, metals are produced from its own feedstock. Since Q4 2016, all nickel converter matte from Nadezhda Metallurgical Plant has been processed at Kola MMC due to the Nickel Plant shutdown.

Kola MMC is currently developing the Zhdanovskoye, Zapolyarnoye, Kotselvaara and Semiletka Fields.
Severny mine (including Kaula-Kotselvaara mine) produces disseminated sulphide ores containing nickel, copper and other saleable components. Severny mine leverages various ore mining methods:
- the Zhdanovskoye Field uses sublevel longwall caving with front ore passes, block caving (limited scope of application), and open-pit mining (at Yuzhny open pit) methods;
- the Kotselvaara and Semiletka Fields primarily use stoping from sublevel drifts and sublevel caving, as well as room-and-pillar short-hole and long-hole stoping (limited scope of application).
Kola MMC’s total ore output amounted to 7.6 mt, up 0.4% (28 kt) y-o-y owing to the development of flank deposits at the Zhdanovskoye Field.
The change in the volumes of ore mined was in line with the annual production plan.
- Zapolyarny Concentrator
The Concentrator produces briquetted copper-nickel concentrate. Nkomati concentrate also undergoes briquetting. Briquettes are delivered to the Smelting Shop to produce converter matte.
In 2017, Kola MMC's Concentrator processed 7,600 mt of ore, up 32 kt y-o-y.
In 2017, the rate of metals recovery in bulk concentrate was above the 2016 level due to a lower content of hard-to-process and talcose ores in the ore mixture.
- Smelting Shop (Nickel)
- Briquetting section (Zapolyarny)
- PGM Concentrator (Monchegorsk)
- Refining Shop (Monchegorsk)
- Tank-Houses 1 and 2 (Monchegorsk)
In 2017, Kola MMC continued improving production processes and proceeded with the maintenance of key production equipment at its smelting facilities.
In Q1 2017, it commissioned a disposal facility for saline effluent from nickel refining operations at Tank-House 2. Tank-House 2 saw further implementation of the project for Nickel Electrowinning from Chlorine Dissolved Tube Furnace Nickel Powder with the Production Volume of 145 ktpa of Electrolytic Nickel.
Kola MMC’s refining facilities in Monchegorsk process converter matte from Nickel's Smelting Shop and Polar Division.
Precious metals produced by Kola MMC are refined at Krasnoyarsk Precious Metals Refinery under a tolling agreement.
In 2017, Kola MMC achieved a higher metal output compared to 2016. The growth was primarily driven by larger converter matte supplies from Polar Division after production reconfiguration.

Finland (Norilsk Nickel Harjavalta)
Norilsk Nickel Harjavalta became part of the Group in 2007. It focuses on processing the Company's Russian feedstock and nickel-bearing raw materials sourced from third-party suppliers.
Norilsk Nickel Harjavalta has a total nickel processing capacity of 66 ktpa.
The facility uses sulphuric acid leaching, the world best-in-industry solution with the metal recovery rates of above 98%.
Founded in 1960, Harjavalta is the only nickel refinery in Finland and one of the largest similar facilities in Europe.
Process flowsheet of Norilsk Nickel Harjavalta
Nickel and copper recovery rates improved on the back of a drop in losses of nickel and copper with ferrous cakes.
In 2017, Norilsk Nickel Harjavalta produced 59.7 kt of saleable nickel, up 11% y-o-y. The growth was driven by the reconfiguration of refining facilities and increased nickel feedstock supplies from Kola MMC.
The third party sales of copper in copper cake totalled 13.4 kt, up 40% y-o-y. This was mainly due to the increased processing of Russian feedstock under the production reconfiguration programme.
The production of saleable palladium and platinum in copper cake dropped by 34% and 55% y-o-y, respectively, after imported feedstock had been replaced with Russian raw materials with a lower content of precious metals.

South Africa (Nkomati)
Nkomati is a 50/50 joint venture of the Norilsk Nickel Group and African Rainbow Minerals. Nkomati's performance is reflected in financial results using proportional consolidation according to our stake and not reflected in other totals.
Nkomati is located 300 km east of Johannesburg, Mpumalanga Province, South Africa.
It is the only South African company to produce nickel concentrate, which also contains copper, cobalt, chrome and PGM.
Nkomati has a substantial resource base represented by disseminated copper-nickel sulphide ores with several major ore bodies. The Main Mineral Zone (MMZ) is comprised of a solid sulphide ore body with a relatively high nickel content. The field also contains a Peridotite Chromite Mineralization Zone with a lower metal content vs MMZ and a relatively high chromium content.
The feedstock produced by open-pit and underground mining operations is processed at concentrators using sulphide floatation. The produced concentrates are then further processed at Kola MMC and third-party companies.
In 2017, total ore mined by Nkomati reached 3.5 mt (attributable to the Group’s 50% shareholding) with an average nickel content of 0.31%.
- MMZ Concentrator with installed capacity of 375 ktpm.
- PCMZ Concentrator with installed capacity of 250 ktpm.
The Norilsk Nickel Group accounted for 8.0 kt of nickel concentrate produced, which is lower than a year ago owing to reduced mining volumes and nickel content in ore processed.
