Boliden is a leading European metals company whose core competence is in the fields of exploration, mining, smelting and recycling. Boliden’s main metals are zinc and copper. Other important metals extracted and refined include lead, gold and silver. The operations are conducted in two Business Areas: Mines and Smelters.

April 30, 2010 - Boliden has acquired Kemira’s
www.kemira.com sulphuric acid plant and business in Kokkola,
Finland, effective as of 1st May 2010. The acquisition will enable Boliden
to conduct its sulphuric acid manufacturing operations at Kokkola in-house,
and thereby gain control over the entire process flow. Sulphur dioxide is a
by-product of both zinc and copper production. The sulphur dioxide can be
refined to produce sulphuric acid, a chemical with a wide range of uses in
numerous sectors, including the artificial fertiliser, pulp and mining
industries. Boliden’s Kokkola zinc smelter in Finland has previously sold
its sulphur dioxide to Kemira Oy, which has, in turn, refined the gas to
produce sulphuric acid. The sulphuric acid plant has an annual production
capacity of approximately 300,000 tonnes and the majority of its production
is sold to local companies, as well as to other industrial facilities in
Finland. The existing contracts will be taken over in conjunction with the
acquisition, which also includes installations, land and around 20
employees. The transaction will not have a significant effect on Boliden’s
results. The parties have agreed not to disclose the purchase price. January 30, 2009 - The prevailing weak market situation is causing Boliden to implement a reduction in copper metal production at its smelters in Sweden and Finland in the first quarter. "This is an extreme situation that affects the whole industry, and it is hard to predict how the market is going to develop. The demand for copper and the by-product sulphuric acid is weak," says Svante Nilsson, SVP for Business Area Market. The reduction, which will be implemented with immediate effect, will see copper metal production cut by approximately 17,000 tonnes in the first quarter of 2009. |
