Pelletizing - LKAB

Luossavaara-Kiirunavaara Aktiebolag (LKAB) is a 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 state-owned since the 1950s. The iron ore is processed to pellets and sinter fines, which are transported by Iore trains to the harbours at Narvik and Luleå and to the steelmill at Luleå ().

Sep 27, 2016· Abstract. Biologically formed nanoparticles of the strongly magnetic mineral, magnetite, were first detected in the human brain over 20 y ago [Kirschvink JL, Kobayashi-Kirschvink A, Woodford BJ (1992) Proc Natl Acad Sci USA 89(16):7683–7687]. Magnetite can have potentially large impacts on the brain due to its unique combination of redox activity, surface charge, and strongly magnetic …

In the real world, lodestones are another name for naturally-occurring magnets. These rare finds, made of the mineral magnetite, attract both pieces of iron and curious onlookers. Most magnetite isn't actually magnetic, and if you magnetise it then it doesn't stay that way for very long.


Iron ore products. Pellets LKAB's iron ore pellets are made from magnetite and have high iron content, around 67 percent. These two factors give a lower environmental impact both during the pelletizing process and during steelmaking, than competing pellets and sintered hematite fines.

Drying and pre-heating increase the strength of the pellets. In the process, large amounts of energy are generated when the magnetite oxidised to form haematite, which reduces the energy requirement by 60 percent. As LKAB has two different types of pelletising plant – straight grate and grate-kiln plants – the drying process varies slightly.

LKAB Minerals supplied high density MagnaDense for Hywind Scotland, the first commercial floating wind park. The design concept is based on a floating spar-type platform which is anchored to the seabed. The floating spar's turbine is much taller than the hull and has a moving rotor that harnesses the strong offshore winds in the North Sea.

Weakly magnetic minerals Non-iron-bearing minerals. Most minerals with no iron content are diamagnetic. Some such minerals may have a significant positive magnetic susceptibility, for example serpentine, but this is because the minerals have inclusions containing strongly magnetic minerals such as magnetite.The susceptibility of such minerals is negative and small (Table 1).

LKAB - Wikipedia

What is Gneiss? Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying composition, while other bands contain granular minerals with an interlocking texture. Other bands contain platy or elongate minerals with evidence of preferred orientation. It is this banded appearance and texture - rather than composition - that define a gneiss.
