The mine is owned by Luossavaara-Kiirunavaara AB (LKAB), a large Swedish mining company. In 2018 the mine produced 26.9 million tonnes of iron ore. [2] The Kiruna mine has an ore body which is 4 km (2.5 mi) long, 80 metres (260 ft) to 120 metres (390 ft) thick and reaching a depth of up to 2 km (1.2 mi).
Uranium mining is the process of extraction of uranium ore from the ground. Over 50,000 tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production.
Kiruna iron ore mine in Kiruna, Norrbotten County. The mining industry in Sweden has a history dating back 6,000 years. [citation needed]Historically, Sweden's most famous mine is the copper Falun Mine in Dalarna, which made a significant contribution to the Swedish economy for several centuries.

Most of the output is transported by rail to the ice-free Port of Narvik, a route named the Northern Circuit. The Port of Narvik has a capacity for 25 million tonnes per year of ore and allows ships of up to 250,000 deadweight tonnes (DWT). A ...
Uranium ore deposits are economically recoverable concentrations of uranium within Earth's crust. Uranium is one of the most common elements in Earth's crust, being 40 times more common than silver and 500 times more common than gold . [ 1 ]
There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material (muck out round), scaling (removing any unstable slabs of rock hanging from the roof and ...
Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling. Beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals , which results in a higher grade product ( ore concentrate ) and a waste stream ( tailings ).
Uranium is produced from the Somair mine at Arlit, 63.4% owned by Orano Cycle and 36.66% by Niger state mining assets company Société du patrimoine des mines du Niger, known as SOPAMIN, and has produced nearly 68,000 tonnes (149,900,000 pounds) of uranium since operations began in 1971; and the Akouta mine at Akokan, owned by Orano Cycle (34% ...
