Norilsk Division accounted for 72% and 42% of the Group’s total copper and PGM end products, respectively.
Nornickel conducts ongoing geological exploration at the Talnakh Ore Cluster deposits in order to increase the reserves of rich and cupriferous ores through operational exploration and follow-up exploration of deep horizons and flanks.
The northern part of the Norilsk-1 Deposit was not explored in 2018.
The Talnakhskoye and Oktyabrskoye Deposits are developed by Taimyrsky, Oktyabrsky, Komsomolsky, Skalisty and Mayak Mines. Polar Division uses simulation modelling for underground mining planning.
The Norilsk-1 Deposit (Bear Creek) is developed by Zapolyarny Mine through open-pit and underground mining.
All ore produced is enriched at Talnakh and Norilsk Concentrators. Talnakh Concentrator processes rich, cupriferous and disseminated ores from the Oktyabrskoye and Talnakhskoye Deposits to produce nickel-pyrrhotite and copper concentrates and metal bearing products. In 2018, the Company resolved to ramp up capacity at Talnakh Concentrator from 10.2 to 18 mtpa.Talnakh Concentrator processed 10.9 mln t of ore in 2020 (up 0.2 mln t y-o-y). Its nickel recovery from ore into bulk flotation concentrate, including the output of metal-bearing pyrrhotite products, increased by 2.0% y-o-y to 87.9% due to the optimised technology for obtaining copper-nickel concentrate deployed at Talnakh Concentrator.
Norilsk Concentrator processes all disseminated ores from the Norilsk-1 Deposit, cupriferous and disseminated ores from the Oktyabrskoye and Talnakhskoye Deposits, and Copper Plant’s low-grade ores to produce nickel and copper concentrates.
As part of its large-scale reconfiguration programme, the Company shut down Nickel Plant, making Kola MMC its new nickel refining hub. Polar Division focuses on the production of converter matte (semi-product sent to Kola MMC), as well as copper cathodes and sulphur.
Thickened concentrates are hydrotransported from Talnakh and Norilsk Concentrators to Nadezhda Metallurgical Plant and Copper Plant. Nadezhda Metallurgical Plant processes nickel-pyrrhotite concentrate and metal bearing products from Talnakh Concentrator, nickel concentrate from Norilsk Concentrator and pyrrhotite concentrate, while also producing converter matte and elemental sulphur.
Copper Plant processes all copper concentrate from both concentrators and handles third-party feedstock to obtain saleable copper cathodes. It also produces elemental sulphur and sulphuric acid for the production needs of Polar Division.
Copper Plant processes slime from the Copper Tankhouse to produce concentrates of precious metals and technical selenium. Precious metals from Polar Division and Kola MMC are refined at Gulidov Krasnoyarsk Non-Ferrous Metals Plant (Krasnoyarsk Territory) under a tolling agreement.
