Hematite Wikipedia

hematite, also spelled as haematite, is a common iron oxide with a formula of Fe and is widespread in rocks and soils. hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 3.it has the same crystal structure as corundum and ilmenite with which it forms a complete solid solution at temperatures above 950 the pelletization procedure consists of agglomerating the ore powder into green balls or pellets and drying and hardening them usually by heating. when wet, the ore particles are held together by capillary forces and surface tension but they fall apart during the drying procedure.
