Contents
● What is being mined?– the most important ores and minerals
● mines and quarries● unexploited resources● enrichment and smelting● recycling
Mined Goods
● Stone and plain rock– crushed stone– sand– gravel
● Ores (metals)
● Minerals
100 000 000 000 kga year
20 000 000 000 kga year
Stone and plain rock
Ores● Finland has a significant part in production of
– chromium (used for coating other metals)– nickel (steel, batteries)– gold (jewellery)– hi-tech metals (electronics)
● Other ores include– cobalt– copper– silver– zinc
Cr

Zn
Minerals
● Limestone● Dolomite● Apatite● Talc● Quartz● Feldspar
● Minerals can be used for example in fertilizers, chemistry and jewellery.
● Limestone is used in construction.
Mines and quarries
In 2007 in Finland there were– 10 ore mines– 16 limestone mines or quarries– 20 mineral or rock quarries
These mines employ about 14 000 people.
Talvivaara is the world's largest nickel producer.
It is also the first mine in Finland to receive permission for gathering uranium in 2012.
In 2012 there was discussion about environmental questions and Talvivaara.
Iron mining is being planned.
Gold is being mined all the way from north to south!
Chromium is rare. Finland is an important producer of it.
In this mine lies the deepest sauna in Finland! It is 1400 metres underground.
Unexploited resources
● Uranium– A Finnish mining company Talvivaaran
Kaivososakeyhtiö Oyj has received permission to begin gathering uranium.
● Lithium– has just been found in Finnish ground– will become more important as it is the material for
electric cars and batteries
● Iron
Enrichment and smelting
Importation of ores for enrichment– Iron ore
● from Sweden and Russia● made into steel
– Nickel● A lot of nickel is imported from
other countries even though Finland does mine a lot of it itself.
Recycling and reuse of metalsin Finland
● well-organized● efficient● better option than
smelting new metal● saves 60–95 % energy● Aluminium recycling in
finland is top-quality.
