Mining in Sweden


The mining industry in Sweden has a history dating back 6,000 years. Sweden's most famous mine is the copper Falun Mine in Dalarna. Income from the Falun mine funded almost all of Sweden's wars throughout its history. Falun mine is the source of the pigment falu red that painted castles, churches and cottages still seen throughout Sweden.
Sweden today is one of the largest sources of iron ore in Europe, with approximately 92% of Europe's iron and 5% of the world's iron reserves. Currently, Sweden's mines produce 80 million tons of ore in Sweden per year, mostly from Kiruna Mine, which in 2008 produced 27.5 million tons of iron. In 2012, Sweden was one of the most active major mining countries in Europe.
Most of Sweden's landmass is geologically part of the Baltic Shield, which also covers Fennoscandia and northwest parts of Russia. The Baltic Shield has the oldest rock in Europe, and is one of the largest and most active mining areas on the European continent. Most Swedish mines are in the Baltic Shield.
The shield, because of its resemblance to the Canadian Shield and cratons in South Africa, may also be a source of gold and diamonds.

History

Sweden has a long history of mining, dating back thousands of years. Sweden's earliest mining company was Stora Kopparberg, which operated on the copper Falun Mine. Many German miners and merchants came into Sweden to join Sweden's mining industry. Because of their influence, iron exports from Sweden went primarily to Lübeck and Danzig in modern-day Poland.

Commodities

Copper

In the Bronze Age, most copper used in Europe originated in places such as Sicily and Iberia and the Levant. For example, a 3,600 year old copper axe was created in Sweden using copper from Cyprus. Europe's economy at the time relied heavily on copper, the major component of bronze.
Sweden's Falun copper mine opened about 1300. It was the largest copper mine in Sweden, and produced two-thirds of Europe's copper needs. The largest industrial work place in Sweden, at its peak in 1650 the mine produced as much as three kilotons of raw copper in that one year.

Iron

Iron, as the major component of steel, is of major importance to mining. Crude steel produced in Sweden in 2017 consisted of 1/3 scrap iron and 2/3 of pig iron made from iron ore. Sweden's iron was important to both Nazi Germany and the Allies of World War II.
During the High Middle Ages, Sweden's iron industry followed the "eastern branch" iron production, using bowl furnace methods rather than the open hearth "bloomery" model favored in England. One of the most important Swedish iron products was osmund, small pieces made from pig iron, weighing no more than 300 grams, suited to the needs of village smithies. Later, production shifted to bar iron.
It was also clear the Swedish iron-smelters were connected to major iron markets outside Sweden, where they also influenced osmund production sold by merchants from the Hanseatic League.

Gold

In the European Union, Sweden is the second largest gold producer after Finland. Sweden may also have large amounts of gold that could be mined in the future.
The name of Swedish mining company Boliden AB comes from the Boliden mine, near Skellefteå, where gold was found in 1924. The Boliden mine was once Europe's largest and richest gold mine, but since 1967 that mine is no longer active. Nevertheless, Boliden AB remains a major producer of gold in Sweden, because their polymetallic mines can produce as much as 2,000 kilograms per year. Some gold is commonly recovered from copper mines in Sweden and Finland.

Impacts on the environment

Kiruna relocation

The Kiruna Mine, the largest iron ore mine pit in Europe, plans to expand operations in the future. The nearby town of Kiruna would be endangered, however, if iron ore is extracted beneath it, which would cause instability in soil and building foundations. In order to resolve this problem, the mining company LKAB plans to move the entire town with its 18,000 people to the east.
One building which will be moved during the relocation is Kiruna Church, a Gothic Revival building built in 1912. Many of the town's other buildings, however, will instead be demolished and rebuilt at a new location by LKAB.
