Boliden Kokkola

Europe's second biggest zinc producer

Boliden’s smelter Kokkola, located on the west-coast of Finland, is the second largest zinc smelter in Europe. The main part of the zinc concentrate comes from Boliden’s own mines, but concentrates are also purchased from other mining companies.

During the production process zinc is extracted to meet the most demanding customer needs. 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.

Thanks to continuous development the smelter is world class in terms of low emissions and energy efficiency.

Did you know that...

Boliden Kokkola reached a historic milestone in August 2018, when it produced its 10th million tonne of zinc cathodes at the elactrolysis.

It’s a staggering amount, 10,000,000 tonnes of cathodes during the plant’s 49-year existence. That’s 10,000,000,000 kilograms, for a total of 555 million cathodes!

Kokkola produces cathodes around the clock, so we are already on our way to making our next million!
