Malmberget mine

The Malmberget mine (Swedish: Malmbergsgruvan) is one of the largest iron ore mines in Sweden. The mine is located in Malmberget in Norrbotten County, Lapland. The mine Malmberget ("The Ore Mountain", Finnish and Meänkieli: Malmivaara) is a locality and mining town situated in Gällivare Municipality, Norrbotten County, Sweden. It had 5,590 inhabitants in 2010, reduced to 927 by December 2020. It is situated 5 kilometres from the municipal seat of Gällivare. The entire Malmberget town was moved in 2020/2021 due to mining activities Malmberget

From mine to port LKAB

The road from mine to steel is a long journey that begins with exploration, which involves testing the bedrock for mineral deposits. If exploration is successful, mining and processing can follow. Our main products from The iron ore Mineral Reserves in Kiruna and Malmberget have decreased in line with mine production, also with some downgrading in the Kiruna mine due to the seismic event in 2020. Mineral Reserves in the Leveäniemi mine in Svappavaara have increased by about 13% to almost 100 million tonnes.LKAB releases Reports on the large increase of Mineral Resources

Process integration in an iron ore upgrading process system

3 Malmberget Pelletising Plants The pelletising plant is the final step in LKAB’s production chain where the aim is to produce iron ore pellet. At the facility in Malmberget there are today two pelletising plants. The first plant (BUV) was started up in the early 70’s. The request for iron ore pellet hasLKAB operates two of the world’s largest underground iron ore mines, the Kiruna and the Malmberget mines. Both use the sublevel caving method for ore extraction. The major iron ore being mined is magnetite with small quantities of hematite. The iron content of pure magnetite ore is 72.36% and that of pure hematite ore is Challenges with Density-Based Grade Estimation at LKAB’s

Mining-Induced Deformation in the Malmberget Mine

Sweden’s LKAB mining company was founded in 1890, though mining in the region goes back to 1660s when the first iron ore sample was collected. The Malmberget sublevel caving mine comprises some 20 orebodies, of which about half of them are in production today.

Degree Project in Technology First cycle, 15 credits

2.2 Fundamentals of iron ore reduction Iron can be reduced from hematite or magnetite. In Sweden, iron ore is mined in the Lapland fields, Kiruna and Malmberget. The iron ore mostly consists of magnetite but a smaller part of Malmberget is hematite [8]. If good energy storage is desired, then magnetite has proven to be the most ideal. MagnetiteLKAB. Luossavaara-Kiirunavaara Aktiebolag ( LKAB) is a state owned Swedish mining company. The company mines iron ore at Kiruna and at Malmberget in northern Sweden. The company was established in 1890, and has been 100% state-owned since the 1950s. The iron ore is processed to pellets and sinter fines, which are transported by Iore trainsLKAB

Characterization of Mertainen Iron Ore Deposit for Mineral

Although the geology and mineralogy of the Mertainen iron ore deposit differ from the other iron ore deposits operated by LKAB, i.e. Kiirunvaara and Malmberget underground mines and Leveäniemi open pit, it seems to be possible with cationic silicate flotation to reduce the silica (SiO 2) content in the magnetite concentrate produced from The iron ore reserves in Kiruna increase from about 700 to more than 800 million tonnes, which means that the life expectancy of the current 1365 main level is extended from 2035 to 2046. In Malmberget the reserves increase by 30 million tonnes to about 300 million tonnes, which also extends the life expectancy above the current main LKAB increases mineral resources and reports rare earth metals

The iron ore mining started in 1741 at the Illuvaara mountain, later known as Gällivare Malmberg and eventually just Malmberget. The first train which transported iron ore was loaded in 1888 this was the beginning of the great iron ore rush which would change the entire area of Northern Lapland.
