whats the difference between hematite and iron ore. Hematite: A primary ore of iron and a pigment, Hematite is the most important ore of iron and it has been used by people as a pigment for at least 40,000 years . difference between hematite and magnetite iron ore
Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.
Magnetite and hematite are common ironbearing minerals that are often mistaken for meteorites. Both minerals can occur as large masses with smooth surfaces that are heavier than typical rocks, but have some features which resemble meteorites.
Apart from that, the magnetic materials are divided into several groups based on the magnetic properties. Examples for magnetic materials include ferrite (pure iron), neodymium (a rare earth metal), magnetite, hematite (both magnetite and hematite are oxides of iron), cobalt, nickel, iron and their metal alloys, etc.

Particular cases of phase transformation in iron oxide minerals, described as natural reactions of magnetite to hematite and synthetic reactions of hematite to magnetite, were chosen. It is observed, in both scenarios, that the transformation obeys the topotaxial and epitaxial relationship, which are well described for the iron oxide system.
As nouns the difference between hematite and magnetite is that hematite is an iron ore, mainly peroxide of iron, fe 2 o 3 while magnetite is (mineralogy) a magnetic mineral, fe]] 3 [[oxygen|o 4, one of the primary ores of iron it has also been called lodestone.

May 01, 2009· magnetite is a spinel (a reverse spinel, actually) and possesses iron in both the +2 and +3 oxidation state. Hematite possesses iron solely in the +3 oxidation state. If you wish the chemical formulae, magnetite is Fe3O4 whereas hematite is Fe2O3. There is slightly more iron, proportionally, in magnetite relative to hematite.
Different Types of Iron Ore. The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.
Hematite is a magnetic material, although its magnetism is weaker if compared to that of magnetite. Hematite stones are very compact and relatively heavy. They can range in color from black to reddishbrown, but by far the most dominant is the silvergray ...
The mineral Hematite is known to form pseudomorphs over Magnetite. Such pseudomorphs are commonly known as Martite, and their appearance may be very similar to regular Magnetite. However, they differ from Magnetite in that they are only weakly attracted to magnetic fields, and have a .
