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 we are world class in terms of low emissions and energy efficiency.

Did you know that...

in 2015, just over 13 million tons of zinc were used worldwide? Almost 60 per cent of all zinc goes to galvanizing, which extends the life of steel and resists rust for up to 100 years.

ZiNiGal

The zinc/nickel alloy ZiNiGal was created to meet the efficiency needs of the galvanizing industry. The addition of nickel to the zinc means that the coating thickness on galvanized steel products can be reduced while also making the surface durable and resistant. ZiNiGal gives steel products a smooth, shiny bright surface and improves wear characteristics, adherence and ductility.

A practical example: in the production of galvanized steel, ZiNiGal has helped one customer reduce zinc consumption by around 900 kg per 25 tonnes of galvanized product.
