| General |
Boliden Harjavalta comprises two
plants – the smelter in Harjavalta, which produces anode copper, and the refinery in
Pori, where copper anodes are refined into copper cathodes. At the Harjavalta smelter
Boliden Harjavalta also carries out nickel smelting on a tolling basis. The cities
Harjavalta and Pori are situated on the western coast of Finland and are at some 30
kilometers' distance from each other. The number of personnel is approximately 415.
The company has a long and creditable tradition starting from the first copper smelter,
established in eastern Finland in 1936. It was transferred to Harjavalta during the final
stages of the World War II. Today's most used metal recovery method, the flash smelting
method, was developed at Harjavalta and implemented in 1949. The copper refinery in Pori
has been operating since 1941.
The Harjavalta copper smelter has the nominal annual capacity of 160,000 tonnes of copper.
Most of the copper produced is cast into copper anodes for further refining into pure
copper cathodes. Sulphur is recovered and sold as sulphuric products.
The nickel smelter of Boliden Harjavalta, operating on a tolling basis, produces nickel
matte for customer needs.
The copper anodes are transported by train from Harjavalta to the copper refinery in Pori
to be refined into cathodes. The nominal annual capacity of the copper refinery is 125,000
tonnes. Besides copper cathodes, the copper refinery produces e.g. gold and silver. |

- 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. |
