difference between magnetite and hamatite ore

Hematite (or haematite) Hematite is the most important ore mineral of iron. It is an oxide mineral and is found in a variety of colours, with red, orange and brown occurring when the iron in hematite begins to rust. There are also several forms of hematite, some of which are: kidney ore, a massive, botryoidal (lumpy) or reniform (kidney shaped) form; specularite, a micaceous (flaky) form ...

The key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. Magnetite and hematite are minerals of iron. Both have iron in different oxidation states, and they are in the forms of iron oxides.

Hematite: A primary ore of iron and a pigment mineral. Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.

Hematite is a shiny, darkcolored reddishbrown stone found in South Africa and all over the world. It consists mainly of iron, which gives it its metallic sheen. Hematite stones are opaque, not the strongest of stones (it has a 56 on the Mohs hardness scale). And they have a strong metallic luster.

Feb 28, 2011 · Magnetite tends to be massive in shape, though you can find octahedral crystals of it occasionally. Hematite also can be massive, but will occasionally be tabular in shape. Hematite is the harder of the two minerals ( vs. ), but not by much.

Difference Between Magnetite and Hematite | Compare the Magnetite is an iron oxide with the chemical formula Fe3O4 Actually, it is a mixture of two iron oxides, FeO and Fe2O3 Therefore, we can show it as FeO·Fe2O3 According to the IUPAC nomenclature, its name is iron (II, III) oxide But, commonly we name this as ferrousferric oxide Magnetite got its name because it is a magnet

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Oct 05, 2016 · Magnetite. Limonite. Siderite. 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.
