Difference Between Magnetite and Hematite Definition

Jan 31, 2018 Main Difference Magnetite vs Hematite. A mineral deposit is a naturally occurring deposit that is unusually rich with a particular mineral.If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called an ore.

Types of Iron Ore: Hematite vs. Magnetite INN

Hematite Fe2O3 2/3 =66%, Magnetite Fe3O4 3/4 = 73%max so Magnetite is higher content Fe and lessor contamination content. Fe2O3 can be turned into Fe3O4 with heat to drive out contamination and

Magnetic Hematite Vs. Hematite Mineralogy Geology eHow

People might assume that magnetic hematite is simply "magnetized" hematite. True hematite, though iron-containing, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite (the artificial material).

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
