Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of

Understanding Iron Ores and Mining of Iron

· Low grade iron ores containing lower iron content need beneficiation activities other than crushing, screening and washing for increasing their iron content. To be competitive, iron ore mining need to be done on a very large scale. There are two mining methods which are commonly employed. They are (i) surface mining, (ii) underground or shaft mining.


It is a low-grade type of ore sample (±35% Fe) with high silica and calcium content (±36%). Based on the fact, that there are appreciable differences in magnetic susceptibility between the desired iron minerals and the gangue minerals, hence, it was suggested that multi-stages magnetic separation may be useful to concentrate this type of ore.

8 Metamorphic Minerals and Metamorphic Rocks – Mineralogy

Low-grade metamorphic rocks are often fine grained. Because they are hard to study and frequently do not represent chemical equilibrium, many metamorphic petrologists prefer to study higher-grade rocks. The photo in Figure shows a serpentinite, an example of a low-grade metamorphic rock.

Synthesis of magnetite powder from iron ore

· Although magnetite is commonly prepared from synthetic iron salts, preparing it from a waste material is quite challenging, yet highly beneficial from a commercial standpoint. The low grade iron ore contains about % iron as hematite (% Fe 2 O 3) and the rest is mostly quartz (SiO 2) with traces of alumina (Al 2 O 3).

[ mineral processing process for iron ore ]

Increasing iron ore demand, coupled with the depletion of high grade hematite ores in the United States, after World War II led to development of lower grade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked
