Boliden's smelters enjoy a strong market position in Europe based on high process-technical skills, flexible smelting processes and the ability to produce high quality metals from complex mined concentrates and recycled raw materials. Boliden is the world's biggest operator in the electronic recycling sector.

The smelters are supplied with concentrates from Boliden's own mines and with concentrates and secondary raw materials from external suppliers.

Boliden's internal copper concentrate production covers approximately 30 per cent of the smelters requirements, while the corresponding figure for zinc smelters is approximately 65 per cent.

A large amount of metal and electronic scrap is used in the copper smelters for recycling.
