Boliden Iron Sand
Skellefteå municipality has introduced restrictions on the use of Boliden Iron sand. Iron sand is a by-product of the Rönnskär copper smelter and has been used as a construction material in the Skellefteå area since the mid-1970s.
Digested sludge used in the restoration of mining areas
Boliden has been using digested sewage sludge in connection with the restoration of mining areas since 2002. The nutrient-rich digested sludge is primarily used to cover waste rock deposits and tailings ponds in order to encourage the establishment of new plant growth and reduce the risk of erosion.
Deliveries of smelting residues to Chile during the mid 1980's
Between 1984 and 1985, Boliden delivered a total of approximately 20,000 tonnes of metallic residues from the Rönnskär smelter to the Chilean company, PROMEL, in the city of Arica. We wish to clarify Boliden's role regarding the deliveries and our position regarding the damages that may be attributable to the deliveries.
The 1998 dam breach at the Los Frailes mine in Spain
In April 1998, a dam breach accident occurred in the tailings pond at the Los Frailes mine in Spain, which was then owned by Boliden's subsidiary, Boliden Apirsa S.L. ("Apirsa"). Boliden is involved in a number of disputes and legal proceedings arising from the accident at the mine.
