Boliden Rönnskär

As the first company in the world, Boliden offer two separate copper products, produced with drastically lower carbon footprint than the global average. One product, Low-Carbon Copper, is produced from concentrate from Boliden’s own copper mines.

The other product, Recycled Copper, has the same emission standards as Low-Carbon Copper, but is produced from secondary raw material such as used electronics and other applications.

Boliden is investing SEK 750 m in a leaching plant at Rönnskär. The plant, aims to extract more metal from residual material. Simultaneously, the amount of waste for disposal in the deep repository at Rönnskär will be reduced. 

The investment is fully in line with the strategy to extract as much metal as technically possible from existing raw materials. This significant improvement in Rönnskär’s resource efficiency will both enhance the smelter’s competitiveness and reduce the volumes of materials for disposal.

The leaching plant comprises a new 45 x 135 meter building located next to the quay in the Rönnskär industrial area. The annual production will total 25 ktonnes of lead sulphate and 25 ktonnes of copper/zinc sulphate.

The investment follows the ongoing investment of SEK 650 m in the deep repository at Rönnskär, which will be taken into operation during 2021.
