Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a complete solid solution at temperatures above ...

Difference Between Magnetite and Hematite Definition ...

Jan 31, 2018  Hematite has unpaired electrons that cause its magnetic properties. It is paramagnetic because it has only ferric ion (Fe 3+).The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore, hematite can be separated from a mixture using high-intensity magnetic separation methods which use magnetic fields with intensity ranging from
