The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics. Further magnetic separation and milling produces even higher iron levels in the magnetite concentrate.
subjected to further separation in a separate cycle. Significant improvements in grade of magnetite concentrate by MG-separation at other iron ore complexes are reported earlier='. MG-separation enables to reduce silica, phosphorus and sometimes sulfur content in iron concentrates---e.g., MG-separation enables to reduce P2~ content in Kovdor
Iron Ore Magnetic Separation. During the dry magnetic separating tests on Cornwall ore, it became evident that this process of magnetic separation was not suitable for this ore, for the following reasons: Dust The ore must be very dry in order to secure freedom of motion between the particles, or poor separation will result.
Dense media separation (DMS) - medium grade; and; Iron ore (coarse grade) Manufacture Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the ...
At present, most U.S. iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet low-intensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to 25 percent magnetic iron, defined as iron occurring in the mineral magnetite.
This series of equipment is mainly aimed at combining the weak magnetic separation and gravity separation, flotation, high intensity magnetic separation of hematite ore, i.e. recovering magnetite by weak magnetic spin, recovering weak magnetic iron minerals by flotation, magnetic separation,parallel process of berkelium burn magnetic separation ...
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. 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.

A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates eco-efficient alternatives for the process design for magnetite iron ore.
