For permanent infrastructure

Zinc is an incredibly important metal for the development of a sustainable society. A thin layer of zinc – known as galvanizing – extends the lifetime of steel structures by preventing corrosion for 50 to 100 years. This means the consumption of iron ore and major carbon dioxide emissions can be reduced and society's investments in infrastructure become more enduring. Out of more than 13 million tonnes of zinc consumed in the world annually, over 60 per cent went to galvanizing. While the construction and infrastructure industries are thus the biggest users of zinc, the automotive and electronics industries are also important end-users, and today China accounts for around half of global zinc consumption. No matter how zinc is used, it is highly recyclable. 

Boliden zinc production

We mine around 350 ktonnes of zinc in concentrates from our mines in Tara, Garpenberg and the Boliden area every year. The majority of this goes to our zinc smelting plants in Kokkola and Odda, where we produce around 500 ktonnes of zinc every year. They also handle recycled zinc.

A large part of our zinc is sold to European sheet metal producers. Most end-users are in the construction and automotive industries. Our zinc meets the industry's highest quality standards, which means it can also be used for making batteries. Today, we are the world's sixth largest zinc producer. To meet demand, we focus on developing alloys that reinforce the end product's qualities.

Did you know that...

more than 90 per cent of the world's zinc production is from zinc blende ores that also include other valuable metals such as lead, copper and precious metals.

The zinc content is usually around a few per cent but may in some cases be as much as 20 per cent.
