Magnetite mineral origin. LKAB Minerals' Magnetite is from our own group resources, ensuring longterm availability and consistent quality. The LKAB mines are located in Kiruna and Malmberget in the northern part of Sweden. The ore is mined and treated at the mine site and railed to one of the two ports – Luleå in Sweden or Narvik in Norway.
The Brockman Iron Formation in the Hamersley province contains significant examples of highgrade hematite iron ore deposits. Magnetite is another iron oxide mineral. It is generally black and highly magnetic, the latter property aiding in the beneficiation of magnetite ores.
For a history of how traces of ancient life have been identified from the magnetic minerals it leaves behind, go to Caltech professor of geobiology Joseph L. Kirschvink's Magnetofossil Homepage. The last entry cites the debate over whether or not the magnetic minerals found in a Martian meteorite are evidence that life existed on the Red Planet.
