Boliden Kokkola Oy

The Kokkola smelter in Finland is the world’s fifth biggest zinc smelter and produces alloys that are used in galvanising. The zinc concentrate is delivered by ship to Kokkola’s own port, both from Boliden’s own mines and from external suppliers. Kokkola uses the in-house developed direct leaching method that enables it to process complex and less pure metal concentrates. Production of sulphuric acid was taken over from Kemira in May.

Boliden Kokkola’s operations are certified in accordance with international standards: the Quality System ISO 9001:2000, the Environmental System ISO 14001 and the Occupational Health and Safety Management System OHSAS 18001.
