This is the crystal structure of goethite, a material made up of iron, oxygen and hydrogen, FeOOH. It’s the main mineral component of rust, and can be often found in the soil. It’s also the main iron ore mineral found in limonite, or bog-iron – which was the starting material for most medieval steels.

Magnetite - an overview | ScienceDirect Topics
These materials have a spinel crystal structure. There are two different interstices that the metal ions can occupy: tetrahedral sites and octahedral sites. In the cubic structure of both iron oxides, one-third of interstices are coordinated with oxygen ions in a tetrahedral structure, while two-thirds are bonded in octahedral sites.

Pyrite Mineral | Uses and Properties
Iron is typically obtained from oxide ores such as hematite and magnetite. These ores occur in much larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur, which reduces its strength. Pyrite used to be an important ore for the production of sulfur and sulfuric acid.

Iron - Wikipedia
As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (fcc) crystal structure, or austenite. At 912 °C and below, the crystal structure again becomes the ...
