31-01-2018· Key Terms: Crystal System, Ferromagnetic, Hematite, Iron, Magnetite, Ore, Paramagnetic. What is Magnetite. Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field; magnetite particles can act like tiny magnets when magnetized.

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe2O3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as the main o…
