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 concentrates as well as from secondary raw materials.

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 25 per cent of the smelters requirements, while the corresponding figure for zinc smelters is 70 per cent.

A large amount of metal and electronic scrap is used in the copper smelters for recycling. These raw materials accounted for approximately 15 per cent of the total raw material requirement in 2010.
