Kaivosvastuu – Outokumpu Chrome Oy

The Kemi Mine opened in 1968, less than ten years after the orebody was found. Chromite ore was extracted from open-pit mines reaching depths of approximately 200 meters until 2005. In 2003, underground mining began. Open-pit mining ended at the Kemi Mine in December 2005 with the final open-pit blasting.
