Hematite (Fe2O3) and magnetite (Fe3O4) are two ores used ...

The molar mass of Fe2O3 is 159.69 and that of Fe3O4 is 231.535. In hematite... The two ores of iron are hematite and magnetite with the stone formula Fe2O3 and Fe3O4 respectively. To determine which of the compounds has a higher percentage of iron per kilogram first the molar mass of the two compounds has to be determined.

Ferromagnetism - Wikipedia

The materials in which the exchange interaction is much stronger than the competing dipole-dipole interaction are frequently called magnetic materials. For instance, in iron (Fe) the exchange force is about 1000 times stronger than the dipole interaction.

Why we use hematite over magnetite as iron ore? - Quora

Also, the magnetite is generally found in ecologically sensitive areas such as the western ghats. The united States, however, use greater amount of magnetite for iron making due to its greater availability there. Check the reserves of other iron ore rich nations/zones like Brazil, Australia, south Africa etc.

Magnetite - an overview | ScienceDirect Topics

Black magnetite, with a specific gravity greater than 5, is easily detected and separated from sediments and tissues by its magnetic properties and the identification can be confirmed by X-ray diffraction.

Types of Metals That Attract Magnets | Sciencing

Apr 25, 2017 · Ferromagnetic alloys are alloys such as steel that contain ferromagnetic metals. Steel is a combination of iron and several other metals, and has a greater hardness than iron. Steel can retain its magnetism longer than iron because of this hardness. When heated to a high temperature, steel will lose its magnetic properties.


remained as low grade magnetite locked In a hard matrix of chert and iron silicates. Had it not been for the great foresight and years of research by Dr. E. W. Davis, Iron mining might no longer be taking place on the Mesabi Range.

Magnetite pollution nanoparticles in the human brain | PNAS

Sep 27, 2016 · We identify the abundant presence in the human brain of magnetite nanoparticles that match precisely the high-temperature magnetite nanospheres, formed by combustion and/or friction-derived heating, which are prolific in urban, airborne particulate matter (PM). Because many of the airborne magnetite pollution particles are <200 nm in diameter, they can enter the brain directly …
