Russian mining group Nornickel is concentrating the processing of its palladium-bearing material in Monchegorsk on the Kola Peninsula, around 200 kilometres from Finland. The company says the facility handles production accounting for about 40 per cent of the global market. Finnish environmental organisations fear that increased emissions could cross the border.
Nornickel has transferred a key stage in its production of palladium and other precious metals from Norilsk in Siberia to Monchegorsk in Russia’s Murmansk region. The change took effect in July 2026 and makes Monchegorsk the company’s sole facility for producing palladium concentrate.
The material being transferred is treated anode slime from Nornickel’s copper operations. Anode slime is a metal-rich residue formed when copper is purified through electrolysis. Despite its name, it is a valuable raw material because it can contain palladium, platinum, gold, silver and other rare metals.
The material was previously transported to Nornickel’s copper plant in Norilsk for further processing. It will now be handled at the group’s metallurgical facility in Monchegorsk.
Nornickel says the change will improve production efficiency and increase the recovery of precious metals. The company describes the transfer as the final stage in a broader restructuring of its production chain.
Monchegorsk gains a strategic global role
Nornickel is the world’s largest individual palladium producer and accounts for around 40 per cent of global supply. This does not mean that 40 per cent of the world’s palladium ore is mined on the Kola Peninsula. Much of the raw material will continue to come from the company’s mining and metals operations in Siberia.
What is being concentrated in Monchegorsk is the processing of Nornickel’s palladium concentrate. The change nevertheless makes the facility strategically important to the world market.
A production disruption at the site could affect supplies of a metal already produced by a limited number of countries and companies.
Palladium belongs to the platinum-group metals. Its main application is in catalytic converters for petrol-powered and hybrid vehicles, where it helps convert carbon monoxide, hydrocarbons and nitrogen oxides into less harmful substances.
The metal is also used in electronics, the chemical industry, dentistry and certain hydrogen-purification processes. Nornickel is attempting to develop new applications in areas including fibreglass, water treatment and battery technology as long-term demand from petrol vehicles is expected to decline.
Russia is the world’s second-largest palladium-producing country after South Africa. The geographical concentration of production leaves the European Union dependent on imports and vulnerable to disruption caused by sanctions, trade disputes or technical failures.
In Finland, Boliden produces small quantities of palladium as a by-product at the Kevitsa mine in Sodankylä. The planned Suhanko mining project in Ranua also identifies palladium as an important potential product. These deposits are not, however, sufficient to replace large-scale imports.
Earlier emissions reached Finnish Lapland
The Finnish Association for Nature Conservation fears that concentrating more metal processing in Monchegorsk could increase emissions into the air and waterways. Its chair, Hanna Halmeenpää, says the effects could be both local and cross-border.
– Major increases in industrial production will undoubtedly cause local and regional emissions into both the atmosphere and waterways. The effects could also reach the Finnish side, Halmeenpää told Yle.
In the early 2000s, she worked on a research project examining the environmental effects of the Monchegorsk industrial complex on nearby waterways. According to Halmeenpää, environmental damage around the plants was clearly visible at the time.
Emissions from the metal plants in Monchegorsk and the Nikel mining district near the Norwegian border have historically included large quantities of sulphur dioxide and heavy metals. The effects of this air pollution have previously been detected in conifer needles in northeastern Lapland.
Sulphur dioxide can be carried over long distances by the wind and converted into acidifying compounds. The pollution can damage vegetation, acidify soil and water and affect human health. Heavy metals can also remain in soil and sediments for long periods.
Emission levels on the Kola Peninsula have fallen substantially since older plants were closed or modernised. Nornickel says emissions from its regional operations declined sharply following the closure of the smelter in Nikel and older production units in Monchegorsk.
This does not mean that the environmental consequences of the concentrated operation can be determined in advance. The impact will depend on production volumes, the design of the processes, the composition of the raw material and the effectiveness of the emission-control equipment.
Nornickel promises controls as Finland monitors air
Nornickel says new gas-cleaning systems will limit the environmental burden. In 2025, the company also launched an automated air-quality monitoring system in Monchegorsk.
The company’s own figures are not a substitute for independent measurements. No cross-border environmental impact assessment has been published showing how the concentrated production could affect Finland.
Pekka Suomela, managing director of the Finnish Mining Association, says there are reasons to monitor developments because of the Kola Peninsula’s history of acidifying emissions. At the same time, he notes that Finland and the rest of Europe depend on imported palladium.
Finland has an extensive network of stations measuring air quality and long-range air pollution. If emissions from Monchegorsk increase and winds carry them toward Finland, changes should be detectable in the monitoring data.
– The positive aspect is that air quality is monitored closely in Finland. If there are any effects, they will be detected, Halmeenpää says.
Measurements can reveal changes in pollution levels, but they cannot prevent emissions. The crucial questions are whether Nornickel’s new cleaning systems can cope with the concentrated production and whether monitoring results are made sufficiently accessible to authorities and researchers on both sides of the border.
