OverviewContentsPropertiesDistribution of depositsBiological occurrencesApplicationsGallery of magnetite mineral specimensMost of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted.

Magnetite & Lodestone | Mineral Photos, Uses, Properties

The importance of iron ore to human society should be obvious, but magnetite has also played a subtler, but equally important, historic role in human civilization. Early on, people discovered that striking magnetite ‘lodestone’ against pieces of iron would magnetize the iron.

Here’s an element factoid for you: Not all iron is magnetic. The a allotrope is magnetic, yet when the temperature increases so that the a form changes to the b form, the magnetism disappears even though the lattice doesn’t change. On a related note, iron isn’t the only metal to display magnetism. Under certain condition, manganese is ferromagnetic.
