Mines

Extensive expertise in mining design, mining methods and a high degree of technological refinement has made several of Boliden's mines among the most productive in the world.

Boliden Mines comprises four mining areas: Aitik, the Boliden Area and Garpenberg in Sweden, and the Tara mine in Ireland. Boliden mines ore from underground mines and open-pit mines.

The ore is transported to the concentrator in the mining area in question to produce concentrate. The mines produce ore with relatively high metal grades, from a global perspective, with the exception of the Aitik mine where the copper grades are low. The majority of the zinc and copper concentrates are processed into metals in Boliden's own smelters. A certain amount of the concentrate is sold to external customers.
