Boliden AB operates through two primary business segments: Business Area Mines and Business Area Smelters. The Mines segment includes major underground and open-pit operations such as the Aitik, Garpenberg, and Boliden Area mines in Sweden, Kevitsa in Finland, and Tara in Ireland. The Smelters segment refines these metals and includes facilities like the Rönnskär and Harjavalta copper smelters, and the Kokkola and Odda zinc smelters. In addition to primary metal production, Boliden is a significant player in metals recycling, particularly electronic scrap and lead-acid batteries. The company's revenue is highly diversified, with zinc and copper being the largest contributors, supported by precious metals and smelting fees.
