Copper

In 2017, we mined 143 ktonnes of copper concentrates. We produce copper from concentrates from our own mines, external mines and recycled material at our copper smelting plants in Rnnskr and Harjavalta. Important end-users for the copper we produce are the construction, electronics, electrical engineering and automotive industries.
