Magnetite - Wikipedia

OverviewPropertiesDistribution of depositsBiological occurrencesApplicationsGallery of magnetite mineral specimensSee alsoFurther reading

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It 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 iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore.

Magnetite - an overview ScienceDirect Topics

Figure 9.8 presents a typical flow sheet for processing a magnetite ore using multiple stages of low-intensity magnetic drum separators. The ore consists predominantly of magnetite and quartz. There are three stages of ball mill grinding and magnetic separation, using low-intensity magnetic drum separators to reject quartz as early as possible. Vibrating screens with apertures of about 150 μm ...

Different Types of Iron Ore - Mineral Processing Metallurgy

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore-BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer...

Ore - Wikipedia

An ore deposit is an accumulation of ore. This is distinct from a mineral resource as defined by the mineral resource classification criteria. An ore deposit is one occurrence of a particular ore type. Most ore deposits are named according to their location (for example, the Witwatersrand, South Africa), or after a discoverer (e.g. the

Estimation of Fe in Magnetite Minalyze

The correlations drawn from the concentration of V within the magnetite/hematite has helped identify distinct zones of ore within our deposits enabling correct classification of differing ore types. The quick turnaround time from core drilled, delivery to, scanning and returned to NIO and the almost instantaneous generation of assay results quickly sorts the wheat from the chaff. This reduces ...
