Where: All of Sweden
When: All seasons
What: Metals
We sometimes see stones and lakes here that are rust-brown. I wondered if that might have something to do with the iron-rich soil, so I looked into those rusty lakes and metals in Sweden.
Thanks to its varied geology, Sweden is rich in all kinds of metals. Let's take a look at the most common ones found here first:
PRECIOUS METALS:
Gold (Au) Gold is found in various parts of Sweden, with significant mines in Skellefteå and Västerbotten. There are also notable gold deposits in Lapland. Gold is used for jewelry, electronics, and as an investment.
Silver (Ag) Silver is often found alongside other metals like lead and zinc. Historically important silver mines can be found in Sala, a town in Västmanland. You can visit these old mines—highly recommended! I'll leave a link below. Silver is used for jewelry, coins, industrial applications, and as an investment.
BASE AND INDUSTRIAL METALS:
Iron (Fe) Iron ore is the most important metal mined in Sweden, with large mines in Kiruna and Malmberget in Lapland. The Kiruna area hosts the largest underground iron ore mine in the world. Iron is primarily used for steel production.
Copper (Cu) Copper is mined in the regions of Skellefteå and Åtvidaberg. The Falun mine in Dalarna was historically one of the most important sources of copper in Europe. Copper is used for electrical wiring, pipes, and coin production.
Zinc (Zn) Zinc is often found together with lead and copper. Important zinc mines are located in Zinkgruvan in the Örebro region and around Skellefteå. Zinc is used for galvanization (protecting iron and steel from rust), alloys like brass, and in batteries.
Lead (Pb) Lead is usually mined together with zinc. The mines in Garpenberg and the Bergslagen region are major producers. Lead is used in batteries, radiation shielding, and certain types of glass.
Nickel (Ni) Nickel is mined in the regions around Skellefteå and Åtvidaberg. Nickel is used in stainless steel, batteries, and coins.
Tungsten (W) Sweden has small amounts of tungsten ore, mainly in the Bergslagen region. Tungsten is used in hard metal tools, light bulbs, and military applications.
OTHER METALS AND MINERAL RESOURCES:
Cobalt (Co) Cobalt is usually mined as a byproduct of copper and nickel mining, mainly in the regions around Skellefteå. Cobalt is used in batteries, alloys, and as a catalyst.
Lithium (Li) Lithium is a relatively new metal in terms of mining in Sweden, but there are exploration projects underway in the regions around Västerbotten. Lithium is used in batteries for electric vehicles and electronics.
Uranium (U) Sweden has uranium reserves, especially in the Västernorrland and Västmanland regions. Mining is limited due to strict environmental regulations. Uranium is used as fuel for nuclear reactors.
And finally, rare earth elements have recently been discovered in the Kiruna area.
WHY ARE THESE METALS FOUND IN SWEDEN?
The presence of various metals in Sweden is due to the unique geological history and structure of the country. Here are some reasons for this:
Geological History Sweden is part of the Baltic Shield, one of the oldest parts of the Earth's crust. This shield consists of pre-Cambrian rocks that are more than a billion years old. Throughout this long geological history, various processes such as volcanism, tectonic movements, and metamorphism have led to the formation and concentration of metals in the Earth's crust.
Mineralization Processes Throughout Sweden's geological history, various mineralization processes have occurred. This means that metal-rich fluids have flowed through cracks and fractures in the Earth's crust, depositing metals there. For example, past volcanic activity contributed to the formation of metals such as copper and zinc in regions like Skellefteå.
Tectonic Activity Sweden lies on the boundary of different tectonic plates, which has led to mountain formation processes and the creation of metallic deposits. The pressure and heat associated with tectonic activity can concentrate minerals in certain areas, such as the iron ore deposits in Kiruna.
Erosion and Sedimentation Over millions of years, erosion and sedimentation have shaped and reshaped the Earth's crust, bringing metals to the surface or concentrating them in certain layers.
SO, WHAT ABOUT THOSE RUST-BROWN LAKES IN SWEDEN?
This phenomenon can be caused by various natural factors:
One of the most common causes of red water in Swedish lakes is a natural phenomenon caused by the presence of iron oxide. When iron-containing minerals dissolve in the water, they can oxidize and form rust, giving the water a reddish color. This often occurs in areas where the rock and soil are rich in iron.
It can also be caused by algae blooms like red tide, organic materials such as humus and tannins, or runoff from mining and industrial activities like in Falun and Bergslagen.
Now, that mystery is solved, I have to say, I was quite surprised that it's possible to find gold here in Sweden. Does that sound fascinating to you too? In Ädelfors in southern Sweden, you can go gold panning in Sweden's first gold mine. I’ll leave you with the link below :-)
