Second largest zinc plant in Europe

With its annual production capacity of 315,000 tonnes, Boliden Kokkola is the second largest zinc producer in Europe. Up to 85% of its production is exported to North and Central Europe, all within EU.

The majority of the zinc concentrate used by the plant comes from Boliden’s own mines in Sweden, Ireland and Finland, but concentrates are also purchased from other mining companies in Europe and overseas.

During the production process zinc is extracted to meet the most demanding customer needs. The main products are pure zinc and zinc alloys. The total amount of zinc products in the portfolio is about 40, containing both pure zinc and tailored products for certain customers and customer segments. The smallest product is a 25 kg slab, and the biggest is a 4,000 kg jumbo.

The majority of zinc is sold to steelworks, which use it to rustproof their own products. Kokkola zinc meets the highest quality demands and is used also, for example, in manufacturing of batteries.
