Roots in the 1960s

In 1967, Outokumpu made a decision to build a zinc plant in Kokkola. At that time, the company had several zinc mines in Finland, but since there was no zinc plant, all the concentrate that came from the mines was exported.

Kokkola was already a major industrial town in the late 1960, where the state-owned majors Outokumpu and Kemira ran several production facilities. The area was full of labour force and available building land, and Kokkola was an excellent choice because of its location next to good transport connections and close to the zinc mines.

Zinc production in Kokkola began in 1969. Over the decades, the plant has been continuously developed through various expansion and development programmes. The ownership of the zinc plant was transferred from Outokumpu to Boliden in 2004 as a part of a corporate reorganisation. In 2010, Boliden acquired a sulphuric acid plant in the vicinity of the zinc plant from Kemira.

Since 2014, the plant’s zinc production process has also included recovering silver from the zinc concentrate. The silver concentrate that is created as an end product is passed on to be refined into pure silver metal.

A long and stable history as well as a great regional significance encourage the company to continue its quality work far into the future.
