Two years before the founding of the LKAB drove the first ore train on with iron from the Malmbergetin Gällivare to Luleå to the recently completed ore port Svartön. In 1899 the line was opened from Gällivare to Kiruna and 1902 all the way to the Norwegian Narvik, which was able to sell the LKAB iron ore year-round ice-free harbor in Narvik world.
In 1898 Hjalmar Lundbohm CEO of LKAB. The geologist is credited with founding the city of Kiruna and until his retirement in 1920, as a key person to the positive development of the company and the region.
1903 took over the company Trafikaktiebolaget Grängesberg - Oxelösund (TGO ), AB Gellivare Malmfält (AGM ) together with its subsidiary LKAB. Four years later, the state goes into the company by buying all preferred shares of LKAB.
In 1954, the company built the first factory in Europe pellets in Malmberget. Three years later, in 1957, the state assumes LKAB with 96 %, the remaining 4% of stay in the TGO. To 100 % state-owned, the company is then since 1976.
1961 opened the LKAB mine in the Leväniemi in the ore field of Svappavaara, which in 1983 had to be closed because of poor market conditions. Subsequently, the mine was flooded. After obtaining the environmental permits LKAB wants to dewater the mine again and put the system back into operation. 1968 opened the LKAB in Svappavaara a pellet plant.
