Hematite and magnetite are the most common types of Iron ore. Roughly 98% of iron ore on the global market is used in iron and steel production. [8] The other 2% of iron ore is used to make powdered iron for certain types of steel, auto parts, and catalysts; radioactive iron for medicine; and iron blue in paints, inks, cosmetics, and plastics.

The Kiruna mine is the largest and most modern underground iron ore mine in the world. [1] [unreliable source?] The mine is located in Kiruna in Norrbotten County, Lapland, Sweden. [1] 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]
Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...
Iron formations can be divided into subdivisions known as: banded iron formations (BIFs) and granular iron formations (GIFs). [ 3 ] The above classification scheme is the most commonly used and accepted, though sometimes an older system is used which divides iron-rich sedimentary rocks into three categories: bog iron deposits , ironstones , and ...
The ironworks was of crucial importance in the development of the ability to use cheap, low quality, high sulphur iron ores worldwide. It was the site of the experiments by Sidney Gilchrist Thomas and his cousin Percy Gilchrist that led to "the basic steel process" or " Gilchrist–Thomas process ".
As of 2023, India is the world's 4th largest exporter of iron ore. [67] The country also accounts for 9.2% of the world's iron ore production as of 2023. [67] In 2021, the value of India's iron ore exports were $4.2 billion. [68] As of 2019, India has the world's 7th largest iron ore reserves, with reserves of 5.5 billion tonnes. [69]
The company went bankrupt in 2015 due to a decrease in iron price by 70 %. [6] The main access ramp is being extended down to the 350 m level, and a new ore elevator is being put in. The estimated ore reserves have been revised up to 35 million tonnes, sufficient for at least 14 years production.
The Kaunisvaara mine is a large iron mine located in northern Sweden in the village of Kaunisvaara in Norrbotten County.Kaunisvaara represents one of the largest iron ore reserves in Sweden and in the world having estimated reserves of 872 million tonnes of ore grading 32.7% iron metal.
