Magnetite is rock mineral and one of the most important iron ore minerals with chemical formula is iron(II,III) oxide, Fe2+Fe3+2O4 .It also as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World. Small grains of magnetite occur in almost all igneous and metamorphic rocks.

Which is correct about Magnetite iron ore? (a) Magnetite is the most important industrial iron ore in terms of the quantity used. (b) Magnetite has the inferior magnetic qualities which is not valuable in the electric industry. (c) It is the finest iron ore with a very high content of iron up to 70%. (d) It has a slightly lower iron content ...

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the …

The magnetite deposits of the Turgai belt (Kachar, Sarbai and Sokolov), in the Valerianovskoe zone of the southern Urals, Kazakhstan, contain a combined resource of over 3 Gt of iron oxide ore.The deposits are hosted by carbonate sediments and volcaniclastic rocks of the Carboniferous Valerianovka Supergroup, and are spatially …

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black; limonite or bog …

Magnetite iron ore is a type of iron ore characterized by its high iron content and magnetic properties. It is one of the major iron ore varieties alongside hematite and goethite. The chemical formula of magnetite is Fe3O4, indicating that it consists of iron (Fe) and oxygen (O) atoms.
