Nornickel upgrades Norilsk Concenrator

24 november 2022
The Company takes further steps to ramp up production capacities at Norilsk Concentrator (part of Medvezhy Ruchey, Nornickel’s subsidiary). Among them is installation of a new crushing unit that will enable to process up to 9.2 mt of ore per year.
The equipment was installed on a tight deadline (two and a half months) amidst the ongoing production. It took some 100 people engaged on a 24/7 basis to dismantle the old equipment, install around 50 tonnes of metal structures and lay down 220 cubic metres of reinforced concrete elements. The large-size equipment (up to ca. 45 tonnes) required two cranes with a capacity of 15 and 50 tonnes.
“Since the idea came up half a year ago, we managed to have all design stages covered, equipment manufactured, and construction and installation works completed. The project is worth RUB 550 m of investment. We also have ambitious plans to upgrade the existing fine crushing unit and the Talnakh ore crushing plant. These are our next targets,” said Vladimir Zaytsev, CEO of Medvezhy Ruchey LLC.
The new crushing unit is currently at the commissioning stage to adjust automation and process parameters for ore feeding and washing. It will be in full swing by the end of November, enabling Norilsk Concentrator to reach the design capacity in 2023.
Norilsk Concentrator became part of Nornickel’s subsidiary Medvezhy Ruchey LLC in 2017. It processes all desseminated ores from the northern part of the Norilsk-1 Deposit and cupriferous ores from the Talnakhskoye and Oktyabrskoye fields to produce nickel and copper concentrates.
The facility’s key shops are its Crushing Shop, Milling-and-Flotation Shop, and Hydraulic Structures and Hydrotransport Shop. Norilsk Concentrator also has two pipelines (operational and back-up) to transport waste tailings to the Lebyazhye tailing dam.
