Apr 09, 2015· Fe 2 O 3 vs Fe 3 O 4. The difference between Fe 2 O 3 and Fe 3 O 4 can be discussed in terms of their chemical as well as physical properties and usage. Both of these minerals are naturally occurring iron oxides. But, most of their properties and usages are different to each other. The natural form of Fe 2 O 3 is called hematite, and that of Fe 3 O 4 is called magnetite. . They both are ...
Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Magnetite Facts Figures | The Magnetite Network. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).
Magnetite weighs gram per cubic centimeter or 5 170 kilogram per cubic meter, density of magnetite is equal to 5 170 kg/m³. In Imperial or US customary measurement system, the density is equal to pound per cubic foot [lb/ft³], or ounce per cubic inch [oz/inch³] .
