Name: Kiruna iron-ore-mine.
Location: Located in Northern Sweden.
Brief history: Mining at Kiruna began over 100 years ago and today it is the world’s largest iron-ore-mine.
Brief description: An underground operation that employs 1 800 people, of which 400 work in the mine.
Mining method: Underground.
Reserves: Total proven and probable reserves are 797 Mt as at December 31, 2004.
Resources: Total measured and indicated resources are 514 Mt as at December 31, 2004.
Geology: Following intense volcanic activity, the Kiruna orebodywas formed at around 1 600 Ma, with the precipitation of iron-rich solutions onto a syenite porphyry footwall. Containing more than 60% iron and an average of 0,9% phosphorus, the ore contains a very pure magnetite-apatite mix.
Major infrastructure and equipment: From the 775 m level haulageto 1 045 m, the KUJ2000 project has integrated the move down with the upgrading of all of the mine’s ore-handling systems. Mechanisms include the new automated rail transport system on the 1 045 m level and uprating the hoists and crushers. Controlled from the 775 m level, seven 500 t-capacity shuttle trains collect ore and deliver it to one of four crushing stations. In two stages, the 100 mm ore is then skip-hoisted to the 775 m level and then to surface.
Future prospects: The next level of mining at 1 045 m will support production until 2018.
Controlling company: LKAB.

Unique features: Kiruna is the world’s largest and most modern underground iron-ore-mine.

Name: Kiruna iron-ore-mine.
he record heap of iron-ore on China’s doorstep just got even bigger, with the increase in holdings so far this year eclipsing the build up seen over all of 2016 as mills produce unprecedented amounts of steel. Stockpiles at ports rose 1.3% to 136-million metric tons, expanding for a fourth week, according to Shanghai Steelhome E-Commerce Co. So far in 2017, they’ve risen 22.05-million tons, surpassing the 20.85-million added last year. →
