We produce mainly nickel matte, an intermediate product based on nickel concentrate. To produce nickel matte, we purchase nickel concentrate from both our own and external mines for processing in the Harjavalta smelting plant. The nickel matte is then sold onto external customers for further processing into pure metals. Our annual production is around 25,000 to 35,000 tonnes of nickel in nickel matte.
We also produce around 1,000-2,000 tonnes of nickel in the form of crude nickel sulphate, a greenish yellow powder that is an important by-product of copper production. At the smelters in Rönnskär and Harjavalta, we extract crude nickel sulphate with a nickel content of between 22 and 27 percent for sale to external customers.
